After upgrading my EeePC to linux-3.3.4-1-ARCH, the system randomly crashed, from time to time, while I was using it (that is not at boot time). It seems to crash more frequently when applications access many files. Sometime an Oops message is displayed, otherwise the system just hangs up without warning.

No more crash since I rolled it back to linux-3.3.3-1-ARCH.

Additional info:
Processor: i686 Intel(R) Atom(TM) CPU N270 @ 1.60GHz GenuineIntel.
Attached log file comes from "dmesg" just before a crash using "dd".

Steps to reproduce:
dd if=/dev/any_partition | strings | grep Oops
(then the system crashes within a few minutes/seconds)
This task depends upon

Yes I can somehow confirm this on one of my i686 machines too.

Does disabling transparent hugepages help?

echo 'never' >/sys/kernel/mm/transparent_hugepage/enabled
Comment by Jochen Maes (Gcool) - Tuesday, 01 May 2012, 17:44 GMT
Experiencing the same issue on one of my machines as well (i686). Transparent hugepages was/is already disabled.
Comment by ybsar (ybsar) - Tuesday, 01 May 2012, 18:01 GMT
Transparent hugepage support is disabled by default (no such file or directory).
Comment by Jochen Maes (Gcool) - Tuesday, 01 May 2012, 19:45 GMT
Fairly daft of me to not try this earlier, but when I set transparent_hugepage to "always", the issue disappears in my case.

This Bug also affects me, but just with the pae kernel from aur ( ), not with the stock i686 kernel.

This seems i686 only am I correct here?
My system is a pentium celeron.
Comment by Jochen Maes (Gcool) - Wednesday, 02 May 2012, 07:28 GMT
Only seeing the issue on my i686 install here as well (also a celeron). Haven't been able to replicate it on x86_64.

Same here. i686 crash during high io.

Same here (i686, atom N270, 1GiB RAM): freeze after 20 minutes of normal usage; trying to unzip a large file (100% cpu load), the freeze is guaranteed in 20 seconds.
Booting with transparent_hugepage=always doesn't seem to help.
With the previous linux 3.3.3 no similar crashes.

Same here. Hangs up during running firefox etc. Had to downgrade to 3.3.3.

Saw same issue here after linux-3.3.4-1 kernel upgrade from pacman. Rolled back to linux-3.3.3-1 and problem went away. I would suggest linux-3.3.4-1 be pulled from the updates until resolved since this causes crashes.

fixed kernel package will appear in 2 hours in repos
