I'll attach the log file which displays the errors and lspci -vv output for the device information. There is nothing breaking on my machine because of this except it seems to be disrupting NetworkManager from working correctly.

any better with latest kernels ? I added a patch to the airo driver to null out pointers on free, so I'm hoping it'll now turn into a null dereference oops that we can get a backtrace out of.
How about I play with it a little today and check it more. The slab errors seem like they've left and I'm not sure if this is related, but this is all I really have now: Jan 10 00:33:44 rhbw NET[2896]: /sbin/dhclient-script : updated /etc/resolv.conf Jan 10 00:33:44 rhbw dhclient: bound to 192.168.1.111 -- renewal in 37889 seconds.

eeeeek, cisco binary-only vpn thing has been known to randomly corrupt memory. CLOSED->DOOMED, unless you can reproduce this problem without it.
