I'm having an issue with an xHCI (USB 3.0 host controller) Express Card. This card works fine on 2.6.37, but on 2.6.38-rc5, when I plug in the card, I get this output in dmesg: Feb 22 16:32:28 xanatos kernel: [ 119.345996] irq 23: nobody cared (try booting with the "irqpoll" option) Feb 22 16:32:28 xanatos kernel: [ 119.346002] Pid: 0, comm: kworker/0:0 Not tainted 2.6.38-rc5+ #745 Feb 22 16:32:28 xanatos kernel: [ 119.346005] Call Trace: Feb 22 16:32:28 xanatos kernel: [ 119.346007] <IRQ> [<ffffffff8109a1f6>] ? __report_bad_irq+0x26/0xa0 Feb 22 16:32:28 xanatos kernel: [ 119.346019] [<ffffffff8109a3fc>] ? note_interrupt+0x18c/0x1d0 Feb 22 16:32:28 xanatos kernel: [ 119.346024] [<ffffffff8109ad7d>] ? handle_fasteoi_irq+0xcd/0x100 Feb 22 16:32:28 xanatos kernel: [ 119.346029] [<ffffffff8100543d>] ? handle_irq+0x1d/0x30 Feb 22 16:32:28 xanatos kernel: [ 119.346032] [<ffffffff81004bb8>] ? do_IRQ+0x58/0xd0 Feb 22 16:32:28 xanatos kernel: [ 119.346037] [<ffffffff8149f5d3>] ? ret_from_intr+0x0/0xe Feb 22 16:32:28 xanatos kernel: [ 119.346040] <EOI> [<ffffffff8126f2d0>] ? acpi_idle_enter_c1+0x7e/0x99 Feb 22 16:32:28 xanatos kernel: [ 119.346048] [<ffffffff8126f2b2>] ? acpi_idle_enter_c1+0x60/0x99 Feb 22 16:32:28 xanatos kernel: [ 119.346054] [<ffffffff8138ac92>] ? cpuidle_idle_call+0x82/0xf0 Feb 22 16:32:28 xanatos kernel: [ 119.346059] [<ffffffff81001906>] ? cpu_idle+0x56/0xb0 Feb 22 16:32:28 xanatos kernel: [ 119.346064] [<ffffffff8149861b>] ? start_secondary+0x1c1/0x1c8 Feb 22 16:32:28 xanatos kernel: [ 119.346068] [<ffffffff81263386>] ? acpi_ns_parse_table+0x2e/0x34 Feb 22 16:32:28 xanatos kernel: [ 119.346073] [<ffffffff81267a8c>] ? acpi_load_tables+0x9c/0x15d Feb 22 16:32:28 xanatos kernel: [ 119.346076] handlers: Feb 22 16:32:28 xanatos kernel: [ 119.346078] [<ffffffffa0123500>] (usb_hcd_irq+0x0/0x70 [usbcore]) Feb 22 16:32:28 xanatos kernel: [ 119.346100] Disabling IRQ #23 I haven't had a chance to bisect yet. Given that there wasn't any big new features added to the xHCI driver in 2.6.38, I don't think my code is the culprit here. Could it be a USB core or ACPI issue?
