ACPI Power Down is broken in 2.6.21.1

ACPI Power Down is broken in 2.6.21.1

[Vladimir Pouzanov]

Hi all,

I have got a problem with Asus F3T notebook and 2.6.21.1 kernel. When I
perform powerdown (with user-space app or alt+sysrq+o) I get "Power Down."
message, but the notebook doesn't turn off. Everything is ok on 2.6.20.

There seem to be no changes in acpi/sleep/poweroff.c so I don't know where
should I start looking for a bug.

F3T is based on Thrion64 X2 CPU (I'm running it in x86 mode with SMP and
PREEMPT).

Sincerely,
Vladimir "Farcaller" Pouzanov

I added this bug to the list of known regressions.

Is the network still connected? Maybe there is a wake on lan
problem with the network device.
