Bug#928891: linux-image-amd64: Kernel crash when using any disk that uses reiserfs

Thanatermesis-2
Package: linux-image-amd64
Version: 4.19+104
Severity: important

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

Dear Maintainer,

When using any partition which uses reiserfs, the kernel crashes

This happens very easily by just using the reiser (v3) filesystem, some
of my external hard disks uses it (so I cannot make use of them), or
partition mountpoints with reiserfs becomes totally unusable and
dangerous

This bug is easily reproducible by creating a new reiserfs partition
(image file probably too) and start using it, so it looks like it
specially affects in RW operations

I suggest to mark this bug as a serious one since there's so many people
using this filesystem, in desktops or servers.

The package is the last one available on the buster branch


Thank you

reiserfs v3 is *not* widely used, and is barely maintained upstream.
Debian hasn't supported installing to reiserfs for a while.

It is quite possible that we will "fix" this by disabling reiserfs
altogether.  In any case, I strongly recommend that you switch to a
better supported filesystem like ext4 or xfs.

Ben.
