Me again. I switched back to my old nic I'm still getting oops. It's
totally reproducible. If I capture an avi file of a couple hundred
megabytes with the program streamer (from the package xawtv) and transfer
another big file through ftp on my internal network I get a kernel oops.
I'm now testing my memory with memtest. Is there another I could check to
try to pinpoint the problem. My oops text is:
