We ran a 2.6.15.1 kernel for months without any problems. Now I tried to switch to 2.6.19.2, and every night when our backup routine runs, the machine locks up. No log entry, no automatic reboot (/proc/sys/kernel/panic is set to 30 [sec]). The display looks like if there was a video error, lots of bad and flickering characters, but it is pretty hard to read the error message. I have an image and a video of that, if you need it. The only thing I could read is something with "ata". After the reboot, the RAID devices are out of sync and need to resync again. Booting up 2.6.15.1 on the same machine cures the problem, everything works just fine, no lockups. Is there any chance of debugging that problem, of finding the culprit? Any help would be greatly appreciated! Thanks Florian
