Alexey,
I just got an OOPS in the CBQ code. When the report is not enough please
let me know.
[1.] One line summary of the problem:
Just booted my system and got an OOPS related to CBQ scheduler.
[2.] Full description of the problem/report:
The problem occured just after setting up network clasifyer and starting the
fetchmail daemon. The system did not respond after this, not even with
sysrq keys. The oops reported process fetchmail.
See rest of info for more detail. Scheduler setup script is below.
[3.] Keywords (i.e., modules, networking, kernel):
Networking in kernel
[4.] Kernel version (from /proc/version):
Linux version 2.6.8.1 (bijwaard@jumbo) (gcc version 3.3.4) #1 SMP Mon Aug 16 14:34:40 CEST 2004
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
ksymoops 2.4.9 on i686 2.6.8.1. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.6.8.1/ (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.
Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
