Sorry, I made this patch reversed by mistake. Use the one attached to
this message, or apply the old one with 'patch -R' :-P

Discussing why it was not RC for Sarge seems pretty irrelevant to me.
It's up to release managers what is RC, and Etch release managers have
stated repeatedly that this issue is RC. I happen to agree with their
position.

>From the comments in patch #9746:

 First attempt to create a new thread was done by Peter Wainwright
 He created a bunch of threads, which were stealing work from a kacpid workqueue.
 This patch appeared in 2.6.15 kernel shipped with Ubuntu 6.06 LTS.

 Second attempt was done by me, I created a new thread for each Notify
 event. This worked OK on HP nx machines, but broke Linus' Compaq
 n620c, by producing threads with a speed what they stopped the machine
 completely. Thus this patch was reverted from 18-rc2 as I remember.
 I re-made the patch to create second workqueue just for notify events,
 thus hopping it will not break Linus' machine. Patch was tested on the
 same HP nx machines in #5534 and #7122, but I did not received reply
 from Linus on a test patch sent to him.
 Patch went to 19-rc and was rejected with much fanfare again.
 There was 4th patch, which inserted schedule_timeout(1) into deferred
 execution of kacpid, if we had any notify requests pending, but Linus
 decided that it was too complex (involved either changes to workqueue
 to see if it's empty or atomic inc/dec).
 Now you see last variant which adds yield() to every GPE execution.
 http://bugzilla.kernel.org/show_bug.cgi?id=5534

Obviously, this version of the patch is not the one which was
reverted. It has already went through some pretty stringent review and
incremental improvement.

I'm not aware of any such policy. We have backported a fair amount of
fixes from newer upstream releases, I don't see what qualifies ACPI as
some magic which should not be touched.

a broken dsdt is a vendor fault.

for sarge the affected range was across all boxes,
here this affects 2 specific hp laptop models.

again i'm highly skeptic about the patch quality.
the semantics of yield() changed fundamentally from 2.4 to 2.6.
afaik only b0rked code in 2.6 needs yield().

I'm going to have to side with maks on this.  The last thing we need at this
point of the release is a complex backported patch, targetted or not, that's
going to require a lot of third-party testing before we can even establish
whether it's caused regressions for other systems.

I think that leaves the best option as ACPI blacklisting, in the kernel, for
those models known to have problems.  I think this is strictly better than
trying to have the kernel give a warning when it detects such a model; it's
more likely to reach the target audience than a note in the release notes;
and it's far less of a support burden overall than trying to add in a
special 2.6.19 kernel in and pretend that support for it could be at all
comparable to that of the main kernel for the release.

Cheers,

Bug#404143: Fans unreliable under load, permanent memory leak

Matthew Garrett
In reply to this post by Maximilian Attems-3
A couple of observations:

* This bug will not cause hardware damage. The hard thermal cutoff
temperature is well below the temperature at which actual damage will
occur.

* It's not clear that the vendor DSDT is broken. It's an unusual
interpretation of the spec, but not necessarily an invalid one - sadly,
the ACPI specification is not entirely clear on every point.

The patch is /probably/ safe, and we've been shipping it in Ubuntu. On
the other hand, previous versions did cause problems on certain other
items of hardware. It's not clear what the best option is, but it's
certainly not a regression over Sarge.

Bug#404143: marked as done (Fans unreliable under load, permanent memory leak)

Debian Bug Tracking System
In reply to this post by Ludovic Brenta-2
Your message dated Wed, 21 Feb 2007 14:17:35 +0000
with message-id <[hidden email]>
and subject line Bug#404143: fixed in linux-2.6 2.6.18.dfsg.1-11
has caused the attached Bug report to be marked as done.

This means that you claim that the problem has been dealt with.
If this is not the case it is now your responsibility to reopen the
Bug report if necessary, and/or fix the problem forthwith.

(NB: If you are a system administrator and have no idea what I am
talking about this indicates a serious mail system misconfiguration
somewhere.  Please contact me immediately.)

Debian bug tracking system administrator
(administrator, Debian Bugs database)


Package: linux-image-2.6.18-3-amd64
Version: 2.6.18-7
Severity: grave
Justification: hardware overheating hazard; requires periodic reboots

(This is not the same bug as #400488 (upstream #7122))

This bug affects several amd64 notebooks from HP, notably the nx6125
and the nx6325; there may be other affected machines as well.

Kernel team, please apply the patches for
http://bugzilla.kernel.org/show_bug.cgi?id=5534

This bug is there merely to remind the kernel team not to release etch
without the patches :) However I'm not sure which upstream version of
linux, if any, contains the patches in the (long) trail of comments.
So, it might be necessary to wait for a few days until the patches
arrive in Linus' tree.

Symptoms:
- under load, the fans fail to turn on when the temperature reaches
  and then exceeds the normal threshold, which is 58°C.
- there is a permanent memory leak in the kernel, even when the system
  is idle.  The leak is visible by looking at
  $ grep Slab: /proc/meminfo         and
  $ grep Acpi-State /proc/slabinfo

Workaround:
- if overheating, shut down the computer and let it cool down; or
  let it shut itself down to prevent a fire hazard.
- if the only problem is the memory leak, reboot.

Consequence: linux-image-2.6.18-3-amd63 (=2.6.18-7) is unsuitable for
release.

The memory leak is described at:

http://www.mail-archive.com/linux-acpi@.../msg03119.html

Today I had to reboot my HP Compaq nx6325 because the kernel was
eating 1.8 Gb out of the 1.9 Gb of RAM in the system, after about 9
days of uptime.  Then I started a hourly cron job to monitor
/proc/meminfo and /proc/slabinfo as described above:

I'm more than willing to help test a kernel package, but I'll be on
[VAC] from 2006-12-23 to 2007-01-03 inclusive.  So, please do not
release Etch just now :)

Changes:
 linux-2.6 (2.6.18.dfsg.1-11) unstable; urgency=low
 .
   [ Jurij Smakov ]
   * Disable CONFIG_DEBUG_FS on sparc32, as it makes the kernel too big,
     resulting in a boot failure. This is ABI-changing, but we cannot
     afford a global ABI bump at that point, so some out-of-tree modules
     in Sid may not load on sparc32 before the corresponding packages
     are rebuilt. Sorry for the inconvenience. (closes: #410497)
   * Add sbus-envctrl-remove-execve.patch which is a backport of changes
     to SBUS envctrl drivers from 2.6.19, making them use
     call_usermodehelper() instead of execve() to call userspace programs.
     Fixes the failure of said drivers to load due to missing execve
     symbol. Thanks to Dann Frazier for testing. (closes: #411135)
 .
   [ dann frazier ]
   * atiixp: fix bug that restricts controller to a single channel.
     (closes: #411023)
   * atiixp: add cable detection support, fixing breakage w/ 40-wire cable
     (closes: #411024)
 .
   [ maximilian attems ]
   * Fix incomplete ipv6 multicast patch from 2.6.16.38. (closes: #410375)
   * UML compile 2.6.16.38 fix forward port completed.
   * Forward port complete IPX checksum patch 2.6.16.34
   * From the 2.6.18 stable queue:
     - IB/mad: Fix race between cancel and receive completion
   * Add 2.6.18.7, thanks gregkh:
     - Fix a free-wrong-pointer bug in nfs/acl server (CVE-2007-0772)
   * Allow ide_generic_all to be used modular and built in.
 .
   [ Steve Langasek ]
   * debian/patches/bugfix/hp-laptop-acpi-blacklist.patch: ACPI-blacklist
     certain HP laptop models (nx6125, nx6325, nc6120, and related) that
     are known to be incompatible with the ACPI implementation in 2.6.18,
     to prevent problems with memory leaks and heat stress at the expense
     of battery control and S3 suspend support.  Closes: #400488, #404143.
