As I have posted a while back, I get oopses in 2.2.12 and 2.2.13.
They are always related to kswapd and they always happen whe the system
has to swap a little. As far as I know, they can be triggered by any application,
and they are irreproducible. Sometimes they happen when the system first
attemps to use kdwapd, sometimes the system runs for as long as 5-6 days
and then Ooops!
I have tried 2.2.12 (RedHat - precompiled and custom-built), and
2.2.13 - No difference. Removed vmware (proprietary modules, scripts, etc.)
- no difference.
After I downgraded the kernel back to 2.2.5 the system seems rock-solid.
I have been trying to generate the oops for six days (I mean trying
hard, forcing the system to _SWAP_A_LOT_). Nothing happens, everything
seems O.K., which makes me believe that the oopses had something to do
with the kernel and not my hardware.
Any ideas/advice/help/appreciated
Arthur
the example of Oops message and my hardware inventory follow:
================================================================================================
ksymoops 0.7c on i686 2.2.13. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.2.13/ (default)
-m /usr/src/linux/System.map (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
