2.6.31 .config used on Intel DX58SO mainboard

Not sure if it's ACPI related or not...

On Intel DX58SO mainboard with 2.6.31 kernel, powering off takes really long.

With 2.6.30 these last steps of shutting down the computer take at most 5
seconds:

Halting system...
[Here up to 5 seconds wait]
Power down...
[Here the PC is turned off, fan, disks etc. is off]



With 2.6.31 with the same .config, it usually takes something around 30-240
seconds, sometimes it takes ~5 minutes; very rarely, it never powers down:


Halting system...
[Here ~30-240 seconds wait, sometimes more]
Power down...
[Here the PC is turned off, fan, disks etc. is off]


I have the latest BIOS installed; this happened with previous BIOS releases as
well.
