Best guess: With 'noapic', I see the "irq 5: nobody cared" message on resume, along with 1 IRQ5 counts in /proc/interrupts (the devices claiming that IRQ are quiescent). Without 'noapic' that must be triggering something else to go haywire, perhaps the AER logic (though that is all MSI, so pr

Quick update: booting with 'noapic' on the commandline seems to make it resume successfully. The main dmesg diffs, other than the obvious "Skipping IOAPIC probe" and IRG number diffs) are: -nr_irqs_gsi: 40 +nr_irqs_gsi: 16 -NR_IRQS:16640 nr_irqs:776 16 +NR_IRQS:16640 nr_irqs:368 16 -system 00:0

kernel panic on resume from S3 - stumped

4 days ago I had Ubuntu Lucid running on this computer. Suspend and resume worked flawlessly every time. Then I upgraded to Ubuntu Precise. Suspend seems to work, but resume fails every time. The video never initializes. By the flashing keyboard lights, I guess it's a kernel panic. It fails from
