Public bug reported:
Using default GRUB parameters ("quiet splash" or even "noquiet"), I'm
unable to reboot or shutdown: the Plymouth circle starts spinning, then
it stops and the system is frozen (altgr+sysrq won't work either).
If I use "acpi=off", I can reboot but obviously the system will not
shutdown (although I can get to a point where it is safe to hold the
power button for 3 seconds).
I also tried "acpi=noirq", "acpi=noapic", "acpi=nolapic", "pci=noacpi"
with no success.
Ubuntu 12.04 worked well, so this is a regression.
Thanks,
MZ
