Hi,
so now and then i get the following oops with isdn - ipppd :
As i log the kernel oopses to /dev/lp0 i saw that some lines of the
output ( the Call Trace lines) aren't complete!

In interrupt handje - not syncing
And this is the ksymoops output:
ksymoops 0.7c on i686 2.3.99-pre9. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.3.99-pre9/ (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.
