Hi,
There is currently a vulnerability in Bind9, which makes it crash. You
may be in this case.

Hi Frédéric,
That was one of my thoughts, but with an unstripped executable it should
be possible to determine a function name or similar for a userspace crash.
After some more investigation, I did find the contents of /proc/modules
interesting:
root@cheeseburger:~# cat /proc/modules
(cut)
snd_page_alloc 9929 1 snd_pcm, Live 0xd000000001fbf000
ath5k 162739 0 - Live 0xd000000001f83000
ath 20320 1 ath5k, Live 0xd000000001f3c00
(cut)
Now I don't know much about the PPC architecture, but comparing with
frame 0 of the backtrace at 0x1f8c1d7c the addresses look similar enough
to imply perhaps the issue lies within ath5k somewhere (which is the
kernel module for the wireless network card).
I think my next move will be to figure out how to build an unstripped
PPC kernel from backports and then raise a bug report with a suitable
backtrace for the ath5k people.
Many thanks,
Mark.
