Subject: PROBLEM: 3.2.14 - Sporadic HARD lockups/__slab_free/intel_pmu_handle_irq->perf_event_overflow
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Kindly Note that kernel is patched against grsec but grsec is not
enabled inside the kernel configuration.
[1.] One line summary of the problem:
Sporadic hard lockups cause server to freeze.
[2.] Full description of the problem/report:
Server is freezing with no output logged to /var/log/messages.
Bug messages are however properly exported and captured by the
netconsole module.
Issue can't be recreated. It occurs sporadicly and hard lockups appears
to be caused by different parts of the kernel at least to me. Not sure
which part triggers them.
[3.] Keywords (i.e., modules, networking, kernel):
intel_pmu_handle_irq
perf_event_overflow
hard lockup
__slab_free
aacraid
[4.] Kernel information
[4.1.] Kernel version (from /proc/version):
Linux version 3.2.14-grsec-clean-sg1 (root@...tbed) (gcc version 4.1.2
20080704 (Red Hat 4.1.2-52)) #2 SMP Wed Apr 11 03:57:50 CDT 2012
Note that kernel is patched against grsec but grsec is not enabled in
the kernel configuration.
[4.2.] Kernel .config file:
Attached
[5.] Most recent kernel version which did not have the bug:
2.6.28
[6.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)

[X.] Other notes, patches, fixes, workarounds:
Freezes like the one described above has been outgoing for us since
2.6.28. Every kernel version we are trying to utilize _after_ 2.6.28
causes sporadic machine restarts, hard lockups and in 99% of the cases
_NO_ output is logged to /var/log/messages. This applies to 2.6.32,
2.6.38.6, 3.2.5, 3.2.9. Sadly but we are still struggling to find stable
kernel for our servers after 2.6.28.
Not sure if this is going to help but before we tried if 3.2.14 will
work correctly for us, we used 3.2.5 and experienced similar lockups on
similar hardware configuration.

WARNING: at kernel/watchdog.c:241 watchdog_overflow_callback+0x97/0xa3()
Not sure if the above information will help you to track this issue down
but any assistance will be greately appreciated. If there is any other
information we can pass let us know. Unfortunately the machines where
these issues occur are in production thus enabling too many debugging
options and often reboots are not a good solution
