Alas:

So your klogd tried to interpret the trace and screwed it up. Then ksymoops tried to interpret klogd's output and screwed it up.
Could you please change you init scripts so `klogd' is started with the `-x' option and then restart your logging daemons? There's a reasonable chance that if you do this your klogd will segfault and stop working when it sees the trace - I'm not sure if Debian have fixed this one.
Alternatively, if you still have that kernel,
cd /usr/src/linux gdb vmlinux x/10i 0xc01e5be0 x/10i 0xc02200d4 x/10i 0xc012bb44 x/10i 0xc01288ad [etc]
That should (finally) tell us where the allocations are occurring. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
