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 ) :

Can you please try to disable HT and suspend?

Well, I think we have a problem with the CPU hotplug.
Can you try to offline-online CPUs (without suspending) and see if that works?

So only 'Hibernation' is enabled in kernel and HT disabled in BIOS ?
If you mean that , sure I can try doing so.
I also could disable Suspend to RAM completly from BIOS as well if you want.

With suspend or hibernation enabled in the kernel, but with HT disabled in the
BIOS.

No, that rather won't work.

Hm, well.
Please apply the appended patch and then try:
# echo 8 > /proc/sys/kernel/printk
# echo 5 > /sys/power/pm_test_level
# echo mem > /sys/power/state
(should wait for approx. 3 sec. and return to the boot prompt)
# echo 4 > /sys/power/pm_test_level
# echo mem > /sys/power/state
(should wait for approx. 3 sec. and return to the boot prompt)
...
# echo 1 > /sys/power/pm_test_level
# echo mem > /sys/power/state
(should wait for approx. 3 sec. and return to the boot prompt)
and see if you can reproduce the problem and for which test level.
[Echoing 0 to /sys/power/pm_test_level restores the normal behavior.]
Greetings,
Rafael

Also box just froze on level 3 but I got a ACPI error at least which I didn't got in any other dmesg till now :
( also patch was tested with HT disabled and Suspend and Hibernation enabled in kernel and BIOS )

Same issues with level 2 and 1.
BTW I found out why my box does not shutdown with acpi=ht. It seems like libata does not like that
acpi mode =) dropping the '... read http://linux-ata.org/shutdown.html , power down manually' message.
That works perfectly with full acpi here.
After all I think all this problems may be some who ACPI related
but the question is why they get triggered by Suspend/Hibernation.
If you want me to test something else just let me know.

Yes. If you have a problem at level n, it should always reappear for n-1 etc.

They certainly are ACPI-related, because the only difference between level 4
and level 3 suspend testing is that some global ACPI methods are executed
at level 3 (in addition to level 4).
Unfortunately, I have no idea what to do next, for now.
I think you can file a bug report at http://bugzilla.kernel.org and put a link
to this thread in there (against ACPI and please add my address to the CC
list).

Also I patched 2.6.23 with that patch and Hibernation works out of box , Suspend to Ram seems to work
fine , just my video card is acting up ( old nvidia card ) I'll play with vbe tool on weekend.
Also I can reproduce that bug in 2.6.23 when I use standby.
I've started to bisect but it will take some time. When I'm done I will post an bug report.
Thanks for your help so far.
