Comment 1 Ben Stringer 2005-09-06 15:10:02 UTC 
Description of problem:
After 1-4 days of operation, some commands start to fail, and the following
message is logged:

Sep  7 00:55:52 pohl kernel: kernel BUG at include/asm/spinlock.h:136!
Sep  7 00:55:52 pohl kernel: invalid operand: 0000 [#15]
(full log to be attached).


Version-Release number of selected component (if applicable):
kernel 2.6.12-1.1398_FC4smp

How reproducible:
Once it begins to occur, it happens quite often. If a particular command fails
(eg. more), it will continue to fail, with the exception of "bash", which is
sometimes logged as the failing process when some other process (eg. rlog) failed.


Steps to Reproduce:
1. Reboot system
2. Leave for 1-3 days
3. Check /var/log/messages or dmesg for evidence of occurrence
  
Actual results:
Many commands either hang or produce a segmentation fault.

Expected results:
Commands run without kernel bug error.

Additional info:
Will try on latest errata kernel also. Hardware is Intel P4 3Ghz, hyperthreading.
Comment 2 Ben Stringer 2005-09-12 02:51:23 UTC 
The PC in question was memtested, and some memory issues were found. After
changing the memory, the PC has run for 6 days without incident. 

Sorry for the noise.
