Extract from /var/log/messages showing logged bug occurrence
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):
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
Many commands either hang or produce a segmentation fault.
Commands run without kernel bug error.
Will try on latest errata kernel also. Hardware is Intel P4 3Ghz, hyperthreading.
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.
