Bug#583686: Kernel exceptions in ext3/journal subsystem
Package: linux-2.6
Version: 2.6.32-13
Severity: important
Hi!
Running sbuild with lvm snapshots seems to hang and the kernel
is spitting out error messages. Seems it is having some trouble! Unfortunately
I'm no kernel expert so if you need something please ask.
Regards
Christoph

This may be related to the infamous sync/umount bug
<https://bugzilla.kernel.org/show_bug.cgi?id=15906>.
Does this happen when sbuild unmounts a temporary filesystem?

This bug report always talks about ext4, which isn't used here. So
I'm not quite sure it's related. Also running the touch / umount snipet
From the bug report runs in acceptable time and doesn't spit out loads
of kernel traces as debootstrap / sbuild / et all does
> Does this happen when sbuild unmounts a temporary filesystem?
Last time it died in the middle of an apt-cache call which doesn't
(as far as I understand it) do any (u)mounts.

It is not specific to ext4.

OK, please make a separate bug report at <https://bugzilla.kernel.org/>
under product 'File System', component 'ext3'. Let us know the bug
number or URL so we can track it.

I'm in suspense now. Did you report this upstream?
If not:
- do you still have access to this hardware, and if so are you
still interested in pursuing this? ("No" is fine, but please do
let us know so we can act accordingly.)
- how do current squeeze kernels behave?
- how about current 3.x.y kernels from wheezy or sid? (The only
packages from outside squeeze that should be needed in order to
test this on squeeze are the kernel image itself, linux-base,
and initramfs-tools.)
- if squeeze kernels do not reproduce the problem, we can declare
victory. Yay!
if squeeze kernels reproduce the problem but 3.x.y does not,
it would be useful to try a few kernels halfway between to narrow
down the range to search for a fix. Historic precompiled kernels
can be found at <http://snapshot.debian.org/package/linux-2.6>.
if 3.x.y kernels reproduce the problem, please report this upstream
and let us know the bug number so we can track it.
Hope that helps and sorry for the trouble,
Jonathan
