Len Brown <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #12 from Len Brown <[email protected]> 2009-07-20 14:42:44 --- Neil, Does this happen only after resume from hibernete, or is it ever seen on a cold boot, or a resume from suspend to RAM? Can you supply a dmesg and /proc/interrupts from 2.6.30? UHCI and yenta share IRQ16. It is possible that when EHCI is initialized, it is somehow enabling the, as yet no loaded, UHCI to provoke and IRQ16 which yenta can't handle; thus disabling IRQ16 pci 0000:15:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 15:00.0 CardBus bridge: Ricoh Co Ltd RL5c476 II (rev ba) uhci_hcd 0000:00:1d.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 uhci_hcd 0000:00:1d.0: setting latency timer to 64 uhci_hcd 0000:00:1d.0: UHCI Host Controller but to complicate things, ahci is also on IRQ 16, but it cuts over to MSI: ahci 0000:00:1f.2: PCI INT B -> GSI 16 (level, low) -> IRQ 16 ahci 0000:00:1f.2: irq 28 for MSI/MSI-X same for i915 video: pci 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 pci 0000:00:02.0: setting latency timer to 64 pci 0000:00:02.0: irq 31 for MSI/MSI-X It would be interesting if "pci=nomsi" fixes this by putting ahci and/or i915 on irq16. If yes, that means that one of those devices is provoking the IOAPIC interrupt on IRQ16, but is not registered on the irq to handle it. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
