Wysocki, linux-acpi 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 ).

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.

Can you try to offline-online CPUs (without suspending) and see if that works? Greetings, Rafael ^ permalink raw reply [flat|nested] 11+ messages in thread

So only 'Hibernation' is enabled in kernel and HT disabled in BIOS ? If you mean that , sure I can try doing so.

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. > BTW I found out why my box does not shutdown with acpi=ht.

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.

To: acpi
I've got Kernel 2.6.5 installed and FINALLY suspend to ram works! I've
got one problem when it wakes up, though, and I'm wondering if anyone
has encountered these as well...
When my system starts up again my usb devices aren't started up.
Unplugging them and then plugging them in doesn't work either, it's like
the usb ports aren't being seen. Anyone have a clue why this might be?
Wes
