acpi shutdown problem on SMP (tyan tiger mp, athlon)

acpi shutdown problem on SMP (tyan tiger mp, athlon)

[Alexander Rauth]

this problem first appeared in vanilla-2.6.2 and is still present in
vanilla-2.6.8-rc4 (vanilla-2.6.1 worked fine)

on shutdown the disks spin down, the VGA switches to powersave, but the
cpu-fans and the power-supply won't power down.

Anyone has a hint for me?

Thanks,
Alexander

Hi

This patch fixes poweroff on my Tyan Tiger S2460 - AMP 760 MP mainboard.
I also test ist on my UP ACPI systems and none broke.

Please verify if it breaks poweroff on other systems.

[alex]

the acpi patches in 2.6.8.1-mm2 fix the acpi shutdown problem on this
board.
