rc4 has been unstable here with the same setup used with rc3. An rc4 kernel
will not stay up 8 hours - rc3 would last days. Stall symptoms differ. Sometimes
X stalls, other times X will not respond but the cursor can be moved. The strangest
was one that happened with X down. In this case sysrq would not output anything
other than the title for the function requested...

I am not sure how to go about getting good debug info for this one.

I am using gentoo on amd64 (a 8450 on 790gx based mb) with gcc 4.3.3
