I have a Sony VPCW218AG netbook that I've dual-booted with Ubuntu 10.10. Unlike the preinstalled Windows 7, Ubuntu will not reboot on this computer. Rebooting from Gnome, using the
reboot command and SysRq+REISUB all don't work; they end hanging with a blank screen.
I have read that Atom netbooks don't have a keyboard controller and therefore the default reboot method,
kbd, won't work. I have actually tried all ten
reboot= parameters listed here; none of them work.
I have also tried disabling ACPI with
noacpi acpi=off for each one; that didn't help either.
Are there any other things I can try to fix the rebooting problem?
