2.6.39-rc3, 2.6.39-rc4: XFS lockup - regression since 2.6.38

["Bruno Prémont" <bonbons@linux-vserver.org>]

[-- Attachment #1: Type: text/plain, Size: 6290 bytes --]

Hi,

Running 2.6.39-rc3+ and now again on 2.6.39-rc4+ (I've not tested -rc1
or -rc2) I've hit a "dying machine" where processes writing to disk end
up in D state.
From occurrence with -rc3+ I don't have logs as those never hit the disk,
for -rc4+ I have the following (sysrq+t was too big, what I have of it
misses a dozen of kernel tasks - if needed, please ask):

The -rc4 kernel is at commit 584f79046780e10cb24367a691f8c28398a00e84
(+ 1 patch of mine to stop disk on reboot),
full dmesg available if needed; kernel config attached (only selected
options). In case there is something I should do at next occurrence
please tell. Unfortunately I have no trigger for it and it does not
happen very often.

Thanks,
Bruno
