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 Ed
