Resume problems

[Gabriel C <nix.or.die@googlemail.com>]

Hi all ,

I'm running current git + aic7xxx suspend patch from  http://bugzilla.kernel.org/show_bug.cgi?id=3062
on a Dell Precision WorkStation 530 MT SMP box ( HT enabled ).

Suspend works fine but on resume I have some problems. 
All CPU's but boot CPU won't come back , everything else seems fine.

After I've played with a lot boot options I found out booting with ' acpi=ht ' will make the CPU's work again but now
I have a problem on Suspend. Everything seems to just go down disks etc but the box itself is for some reason still on.
So I've tested reboot=<> options with no luck.
( after waiting 5 minutes to be sure everything is really off I can just hit power button). On resume now everything is fine.

I'm not really sure what is wrong here acpi/hibernation/cpu-hotplug or a mix of all so I'm CC'ing linux-acpi as well.
The only thing I noticed is the 'Breaking affinity for irq XX' on suspend without acpi=ht messages.

I can't even tell whatever other kernel versions are working because aic7xxx driver didn't got suspend support till now 
( or at least never worked here ). I know suspend worked fine on windows with that box.

There is my config and dmesg ( good and bad one ) :
