I bring my ppp0 interface up, setup various traffic shaping and policing
filters [1] (Bert Hubert's excellent 'wondershaper').
When I 'killall pppd', the kernel crashes [2].

Decoded through ksymoops.
---
ksymoops 2.4.9 on i686 2.6.0-test5. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.6.0-test5/ (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

Hi,
thanks for the report, it seems that there is something
different in tc api on 2.6. I'll download it in a few
days and try your setup.
Next conversation please privately to me (we don't need
to bloat lkml).
