Package: linux-2.6
Version: 2.6.32-38
Severity: important
Tags: upstream

Hi,

the lockup happened on unlinking a large file (several GB) on XFS on fibre
channel storage (qla2xxx module).  We experience very simiral trouble on
this machine though, using other kernels (from stable, stable-backports and
sid as well) and other fs/storage combinations (ext4 on local Dell PERC
controller).  This would normally suggest a HW problem, but this time it's
unlikely IMO.  The machine is new and survived many hours of memtest86-ing. 
Unfortunately we have no second identical machine to replicate it.  The only
HW issue I admit is the availability of newer BIOS, which will be flashed
next week (sorry if you find this to be an obvious reason of the problem).

As I said, the other kernels crash too showing similar backtraces.  I think
the (eventual) kernel bug may relate to relatively unusual configuration of
this machine, which is a NUMA with 64GB RAM, getting probably not that much
beating (I mean testing) as the more common desktop PCs.  Could the unending
find_get_pages indicate slab corruption perhaps?

The full boot-time dmesg output may be found on

http://joni.heaven-industries.com/~egon/tornado-dmesg.txt

The bug is not too easy to trigger, so I hope there's another way to look
for it than bisecting 5 years of kernel commits...  On the other hand, I'm
of course ready to spend a time on it if it helps to make the kernel better
:).

Thanks,

Egon

Thanks for checking.  Marking accordingly.

The intel_idle driver was introduced upstream in the 2.6.36 merge
window and enabled in Debian kernels in 3.1.0-1~experimental.1.
It would be interesting to hear how a recent kernel built with
CONFIG_INTEL_IDLE=n behaves, to confirm that that is actually what
fixed it.

(If building from source[1]: "make nconfig" -> Power management and
ACPI options -> CPU idle PM support -> Cpuidle driver for Intel
Processors.

Another way would be to try 3.1.0~rc7-1~experimental.1 from [2].)
