Keyboard response, mouse movements, display refreshing etc. General input/display sluggishness. Did something break IRQ handling somewhere? I need to validate if this happens with X not running also if it is i915 related somehow.

There were a lot of changes to PCI and ACPI for 3.9. Probably best to each file a bug at bugzilla.kernel.org with: Last known good kernel version -- For both good and bad kernels (preferably as attachments) -- /proc/interrupts lsusb lspci dmesg and reply back with the bugzilla #. It may be necessary to bisect this problem. Regards, Peter Hurley PS - I know it can be difficult to get those things on the bad kernel. It's easier if you boot to console. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
