Somebody in the thread at some point said: > Sorry--no useful log messages. The final line on the screen was > something like "Fatal Exception in interrupt, not syncing". Not much to go on here, but I've seen apparently severe brain damage caused by problems with interrupt allocation changes between kernels: once that was resolved the issues went away. So I think especially since there isn't much else to try, I would hit 'A' at the grub boot menu, and append stuff like acpi=noirq and pci=biosirq to the kernel commandline. They won't help if the actual problem is elsewhere but it's worth a go. Even acpi=off might be worth it just as a test. -Andy
