| |
After some hours under heavy load (=3) I got the following messages in my logs, here run trough ksymoops. At this time there were running gimp with xsane, gimp-print and setiathome, which I had forgotten to stop. There was about 60 MB in swap without much change, swapspace is about 1GB, memory 512 MB. I am running Debian woody on an Athlon 700. The bug is not easy reproducable. I have been running 2.4.19-pre10aa2 for several days without ever seeing it. The real funny thing is: When I stopped X and tried to reboot, the same thing happened, this time with syslog. Besides the aa-patches there were no other patches in the kernel but only the Nvidia-driver, which does not seem to be involved, however.
ksymoops 2.4.5 on i686 2.4.19-pre10. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.19-pre10/ (default) -m /boot/System.map-2.4.19-pre10 (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.
