During the writing of a CDRW, I had a pair of oopses. System uptime was
48 days, CD writing has never failed before. Below are the OOPSes after
being passed through ksymoops 2.3.5 . If anything interesting comes of
this, I'd be interested in hearing it, so could you cc me any replies?
The Kernel is RedHats 2.2.16-1.
Thanks,
Walter
