------- Comment #124 from [EMAIL PROTECTED]  2008-01-01 22:15 -------
This error is NOT corrected with the latest X61s BIOS.  I have a new X61s I
just recieved a few days ago; it exhibits this behavior with BIOS version 1.11:

    thinkpad_acpi: ThinkPad BIOS 7NET30WW (1.11 ), EC 7MHT24WW-1.02

It's strange that I have 1.11, because 1.10 appears to be the latest version
available on the web site.  It must be because my system is so new.  I am going
through the process of configuring the system and troubleshooting any errors in
the logs, and this was one of the first ones I found:

    kernel: irq 20: nobody cared (try booting with the "irqpoll" option)
    kernel:  [<c045b16a>] __report_bad_irq+0x36/0x75
    kernel:  [<c045b380>] note_interrupt+0x1d7/0x213
    kernel:  [<c057ae99>] usb_hcd_irq+0x21/0x4e
    kernel:  [<c045a807>] handle_IRQ_event+0x23/0x51
    kernel:  [<c045bb0b>] handle_fasteoi_irq+0x86/0xa6
    kernel:  [<c045ba85>] handle_fasteoi_irq+0x0/0xa6
    kernel:  [<c04074c3>] do_IRQ+0x8c/0xb9
    kernel:  [<c0405b6f>] common_interrupt+0x23/0x28
    kernel:  [<c05382e6>] acpi_idle_enter_simple+0x17b/0x1f1
    kernel:  [<c0537f40>] acpi_idle_enter_bm+0xc3/0x2ee
    kernel:  [<c05a2399>] cpuidle_idle_call+0x5c/0x7f
    kernel:  [<c05a233d>] cpuidle_idle_call+0x0/0x7f
    kernel:  [<c040340b>] cpu_idle+0xab/0xcc
    kernel:  =======================
    kernel: handlers:
    kernel: [<c057ae78>] (usb_hcd_irq+0x0/0x4e)
    kernel: Disabling IRQ #20

This occurred about 10 minutes after boot, with radios enabled.
Also note that GSI 19 (level, low) -> IRQ 20.
