That "Unable to access resume device (/dev/sda3)" isn't normal, it usually says something different IIRC. Therefore I would guess it can't talk to your drive properly. Recent kernels couldn't bring up a network device on one machine here, staring at it further /proc/interrupts showed 0 interrupts associated with that device. Adding pci=biosirq to the kernel commandline got that working again, so give it a try. Press 'A' at the grub prompt and addit on the end of the bad kernel's commandline. -Andy
