Hello -- there is a lot of confusing and incorrect howto's, etc. out there.
I was using raid0 with kernel 2.2.5 just fine. I have upgraded the
kernel to 2.2.12 in an effort to solve a SMP kernel gen problem, and I can
not get raid0 to work at all.. Any advice, including rtm is fine if
given the real manual or doc.
