What is wrong with kernels 5.X on sparc64 ?

Miroslav Zubcic
Hi people!

Couple months ago, I've got two Ultra 45 workstations.

Cleaned them up, filled with memory and disks, and since Solaris 10 is
too old, 11 doesn't work on UltraSparc IIIi procs, Linux, namely Debian
was most logical choice.

I have bullseye/sid installed in md raid1 + LVM configuration and hoping
to convert this into LXC containered services machines - a system level
virtualization.

I've managed to get some things with mmap MAP_FIXED on sparc64 fixed by
lxc people ( https://github.com/lxc/lxc/issues/3262 ) and successfuly
created first test containers today!

But I have one nightmare with this machines: 4.19.0-5-sparc64-smp is the
last really stable kernel I can get to work there. With all other
updates to kernel image, system panics often, specially when running
systemctl command manually (enable/disable actions) or when called from
apt. I have even tried with manually compiled newest 5.4.1 and 5.5
kernels, but no luck.

The blues usually goes like this (OBP on serial):

Processing triggers for libc-bin (2.31-0+sparc64) ...
Processing triggers for systemd (245.2-1) ...

varnava login: [12438.966956] Unable to handle kernel paging request in

Looks like almost always this is triggered from systemd.


Does anybody have some information or experience with this phenomenon?

Cool, thanks for your contribution for Linux on SPARC.

I think I have seen instability issues on the one IIIi machine we have
as well as this machine is running 4.19 for that reason. Other machines
such as the T2 or later models don't show any issues.

So, I think this issue needs to be bisected and reported to the SPARC
Linux kernel mailing list [1]. I'm CC'ing Meelis Roos who has been doing
a lot of kernel regression testing on sparc64 in the past and might have
already found the problematic commit.

Hi Adrian,

Ok since now I have plenty of time during this global stay at home
times, I'm willing to do any debugging you propose, test things etc.

Here is more info on machine:

1. Two kernel panics from my 1st mail was from different kernels.
Unfortunately, the second one (with apt remove exim) was from couple
months ago.

This are kernels which I have in GRUB:

4.19.0-5-sparc64-smp
5.3.0-2-sparc64-smp
5.4.0-3-sparc64-smp
5.4.0-4-sparc64-smp
5.4.1
5.5.0

Last two are compiled from source. Only 4.19.0-5 works.

root@varnava:~# cat /proc/cpuinfo
cpu : TI UltraSparc IIIi (Jalapeno)
fpu : UltraSparc IIIi integrated FPU
pmu : ultra3i
prom : OBP 4.30.4 2009/08/19 07:14
type : sun4u
ncpus probed : 2
ncpus active : 2
D$ parity tl1 : 0
I$ parity tl1 : 0
cpucaps : flush,stbar,swap,muldiv,v9,ultra3,mul32,div32,v8plus,vis,vis2
Cpu0ClkTck : 000000005f5e1000
Cpu1ClkTck : 000000005f5e1000
MMU Type : Cheetah+
MMU PGSZs : 8K,64K,512K,4MB
State:
CPU0: online
CPU1: online



- Debian system is routinely up to date with packages.

- OBP has the latest patch which I obtained:

Sun Ultra 45 Workstation, No Keyboard
Copyright 2009 Sun Microsystems, Inc.  All rights reserved.
OpenBoot 4.30.4, 14336 MB memory installed, Serial #68142416.
Ethernet address 0:14:4f:f:c1:6d, Host ID: 840fc16d.


So, the problem is usually triggered by systemd or it's systemctl. Maybe
some new fancy syscall or who knows what. :-)

You will have to build your kernel from source and boot that, then
bisect as explained in [1].

This will involve a lot of kernel rebuilds and machine reboots but
you will eventually figure out what broke the kernel on your
machine.

Thank you for this docs pointer. I'm cloning linux.git now and reading
what is git-bisect option anyway. Looks like I will have to run perl
script which will find the maintainer of the minor peripheral driver
"kernel/cpu.c". :-)

I'm reading now how kernel things are functioning in this decade,
because apart from two kernels on this sparc in past 2-3 months, I have
actively compiled kernels 12-15 years ago last time!

P. S.
Are there any special options for compiling or pre-configuring kernel
for debugging in the cases like this? CFLAGS="-g" or something like that?

Not really necessary. You just use bisect to find the commit which introduced
the regression and then send an email to the sparc-linux Linux kernel
mailing list and CC the author of said commit. Usually the author will
figure out quickly what mistake they made.

Yeah, you basically just have to compile your kernel for debugging these
days.

But it's very simple:

$ git clone https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
$ cd linux
$ git bisect start
$ git bisect good v4.19
$ git bisect bad v5.4

BUILD

Then:

$ cp -av /boot/config-$(uname -r) && yes | make oldconfig
$ make && make modules_install && make install && update-grub # update-grub may not be necessary
$ reboot

If it crashes:

$ git bisect bad

If it works

$ git bisect good

Then jump back to BUILD and repeat until git tells you the bad commit.

No. Bisecting doesn't require any debugging. You just build and test kernels
using a bisect algorithm until you found the bad commit.

My test matrix is publicly available at
https://docs.google.com/spreadsheets/d/1nCMi_lQWA0q97VPh5m7zP3SDpw6NiVm6tRxQxVww7-o/

Here, my Ultra 45 has some stability problems with 5.2 and 5.3 and failure with 5.4.
The failures looked same as with Netra 240 (for some reason, 5.3 workd there but 5.2
and 5.4 did not) - had something to do with RCU frequently. I never came to reporting
this fully since I could not exactly pinpoint it, then I started two office moves in
parallel and the quarantine came after that so I did not manage to set up my testbed
in the new office yet.

Looking for some notes - see below for some other crash notes - but no successful bisect.
However, there was a on irc (hopkirk, I think) who had a working 5.4.2 kernel config for
his Ultra45 with gcc-8.3.0 (I only tested with gcc-9).


Also, it appears I have some sparc with me at home - Ultra 45, E420R,Fujitsu M3000
(does not run Linux) and V445 with something broken (probably power backplane).

I might want to install Linux on E420R but do not have FC-AL disks with me.
If I get the disks, what's the state of Debian-ports installer - is it worth trying on sparc64 now?

So I reconnected and started the Ultra 45. It boots up with 5.4 (with warnings in dmesg)
and whatever Debian I had in December 2019. It did successful git fetch but died soon
after that with something that ended in this below. WIll try curent kernel to id I succeed.

Re: What is wrong with kernels 5.X on sparc64 ?

There are no known issues with debian-installer on sparc64 besides the
occasional problem with packages not being installable due to the lack
of cruft support in Mini-DAK in Debian Ports [1].

The only permanent issue that is known is that keyboard input on the serial
console may be flaky in some cases.

Re: What is wrong with kernels 5.X on sparc64 ?

In reply to this post by Meelis Roos
I looked up my old bug postings on Netra240:
https://lkml.org/lkml/2019/11/18/205
https://lore.kernel.org/netdev/6d3e3d29-f23a-dd49-6b4b-f7b6bf7398ab@.../T/

I now remember that I could not produce a working kernel on Ultra 45 - debian-ports 5.2 kernel worked,
self-compiled 5.3, 5.4-rc4, 5.4-rc8, 5.2 did not work. now 5.6 also did not work.

> So I reconnected and started the Ultra 45. It boots up with 5.4 (with warnings in dmesg)

5.6.0 built with gcc-8.3.0 booted up but died during git pull:

Re: What is wrong with kernels 5.X on sparc64 ?

Meelis Roos
Tried 5.6+git as of today, compiled with ccc-9, on Ultra 45.
Fails - here is dmesg in case it gives some hints to somebody. It fails
with a oops and chain of warnings, starting with
Kernel unaligned access at TPC[7fc7f0] tty_reopen+0x10/0x100
One bunch of these unaligned accesses seem to be around tty code.

I started kernel configuration bisection in December but I do not remmeber the details
(gcc 8 I think) so I need to redo it from start to see what exactly is the working configuration
(is the one from hopkirk reproducibly working for me, first).

Re: What is wrong with kernels 5.X on sparc64 ?

I restarted the kernel config bisection using 5.6.0-12706-gb032227c6293 and current gcc-9 (9.3.0 - Debian 9.3.0-10).
So far I have not found a working configuration yet.

 From previous bisection saved configs and notes I came to a preliminary conclusion that when I turn off SMP from
working configuration, I get a nonworking configuration that differs a lot (different RCU implementation chosen etc).

I installed Debians latest UP (5.5.0-2-sparc64) and SMP (5.5.0-2-sparc64-smp) kernels on my single-CPU Ultra 45
and they both work for simple "apt update && apt install some-single-package" test.
Earlier 5.2.0-3-sparc64 kernel also works well for compiling other kernels.

Will continue searching for a working config and then config bisection to find something more precise.

I have found a configuration from previous testing that gives me a working kernel with gcc-9.3. Bisecting the
configuration now - it appears I have to "make clean" before each compilation or I will get partly old kernel that
behaves differently when recompiled after "make clean".

This hypothesis still seems to hold with gcc-9 (my latest working kernel is SMP and a nonworking one is !SMP).

Will keep bisecting.

Also, 5.5.0-1-sparc64 works.

Too early conclusion - compiled and installed a kernel but crashed on shutdown (for reboot):
