I'm trying to suspento to ram from init 1, with all external devices unplugged and all modules unloaded. Seems to suspend fine, but wakeup generates a reboot. Again, how could i try to understand what's going on if the machine just reboots? Thanks, Alberto # lspci 0000:00:00.0 Host bridge: VIA Technologies, Inc.
