Best guess: Booting with 'noapic', I see the "irq 5: nobody cared" message on resume, along with 10000 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 probably not). I'm flying blind on those boots. I bet that, if I can recall how to re-enable IRQ5, I'll see it continuously asserting. Chipset or BIOS bug maybe. I don't know if I had AER enabled under Lucid, so that might be the difference. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1094412 Title: Precise does not resume from S3 - kernel panic on resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/1094412/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
