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
root@cheeseburger:~# cat /proc/modules
snd_page_alloc 9929 1 snd_pcm, Live 0xd000000001fbf000
ath5k 162739 0 - Live 0xd000000001f83000
ath 20320 1 ath5k, Live 0xd000000001f3c00
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.
