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 00:0a: [mem 0xfec00000-0xfec00fff] could not be reserved +system 00:0a: [mem 0xfec00000-0xfec00fff] has been reserved and a new warning about irq 5: nobody cared (try booting with the "irqpoll" option) I'll see if I can sort out further differences, but I thought it was worth sending this new info along, anyway. It did not require 'noapic' on the Lucid (2.6.32?) kernel On Sat, Dec 29, 2012 at 9:34 PM, Tim Hockin <thoc...@hockin.org> wrote: > Running a suspend with pm_trace set, I get: > > aer 0000:00:03.0:pcie02: hash matches > > I don't know what magic might be needed here, though. > > I guess next step is to try to build a non-distro kernel. > > On Sat, Dec 29, 2012 at 1:57 PM, Rafael J.
