PCI: Disabling Via external APIC routing Curiously, this line appears in 2.6.3, but not in 2.6.7 or 2.6.9 dmesg -- even though all the configs build in IOAPIC support. Can you forward the /proc/interrupts from 2.6.3, and from 2.6.9 with and without acpi=off? do you see a significant change in /proc/interrupts before and after the sensor-provoked slowness starts? if you build 2.6.9 w/o the CONFIG_ACPI_PROCESSOR and boot w/o cmdline params, do you still see slowness? if you boot 2.6.9 with these parameters, do you see any additional dmesg lines? acpi_dbg_level=0xF acpi_dbg_layer=0xFFFF3FFF thanks, -Len - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
