I also reported an oops that traced to raid0_map about a month ago. I can
repost it, but basically my system has very similar specs to yours: dual
PII (450mhz) running 2.2.4 + raid0145-19990309. My system also had
another patch installed, the DAC960 hardware RAID controller patch, which
is a very non-intrusive patch. My stack trace was:
>>EIP: c01766ee <raid0_map+8a/118>
Trace: d08b9000 <driver_template+e270/392bc>

Basically identicial. I have heard nothing about it though.
