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. ... Oct 22 15:02:28 lara [ 49.618795] Enabling non-boot CPUs ...

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 ) : http://194.231.229.228/suspend/acpi=ht_working_dmesg.txt http://194.231.229.228/suspend/dmesg_broken_cpus_on_resume.txt http://194.231.229.228/suspend/config Regards, Gabriel - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
