Hello
I had the following reproductible kernel oops while using gnomemeeting.
Start: artswrapper gnomemeeting
Receive a call ==> oops
Pascal
ksymoops 2.4.5 on i686 2.4.19-19mdkenterprise. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.19-19mdkenterprise/ (default)
-m /boot/System.map-2.4.19-19mdkenterprise (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.
Warning (compare_ksyms_lsmod): module reiserfs is in lsmod but not in ksyms, probably
no symbols exported
