I have this situation occurs repeatably: every time I use bladeenc from
http://home1.swipnet.se/~w-82625/ to encode some wav file I ripped off my
music CD, the kernel will oops at somepoint. I ran the oops output through
ksymopps, here is the output: please let me know if you need more information.
