from the just missed rc4 department:
I recieved this BUG last night on my laptop and it was shortly followed
by a warning from the kernel. I doubt that I can reproduce this. It
happened under a light load. I was doing some emailing using thunderbird
(er.... icedove.....). let me know if there's anything I can do to help
debug or if there's more info I can get that would help you figure out
what went wrong.
Thanks,
Greg
