TIA > <snip> Please file a sighting here: http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI Category: config-interrupts Please note if this has always not worked, or if a previous version of Linux worked. Please attach the dmesg and /proc/interrupt from the acpi=off boot; and the same for the boot with no boot parameters. Please attach a single copy of the output from acpidump, and the output from lspci -vv. thanks, -Len - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
