Yeah, I feel like I'm fumbling in the dark with unstable kernels, and nothing seems likely enough to merit seriously trying to do any hacking :( esp. since I'm still busy wrapping my head around cfengine2 and fai to keep my clusters manageable. At least I'm confident the hardware is ok. I've run memtester a lot while the system is up and running (and memtest86 for a few hours during some reboot downtime), so I don't think there's a problem there. > What gcc did you use > to compile your kernel? Debian Sarge's default compiler, gcc 3.3.5.
