Just log in over a network connection. Or get a USB-2.0 > hub and plug the mouse/keyboard into that hub. using a usb2 hub an unloading the uhci-hcd module, i've been testing for a while, but again got the message: [20699.107441] irq 16: nobody cared (try booting with the "irqpoll" option) [20699.107445] Pid: 267, comm: irq/16-ahci Tainted: P 3.1.0-rc8+ #16 [20699.107447] Call Trace: [20699.107453] [<ffffffff810d27b6>] __report_bad_irq+0x36/0xe0 [20699.107456] [<ffffffff810d2bfd>] note_interrupt+0x14d/0x210 [20699.107460] [<ffffffff81069527>] ? local_bh_enable+0x57/0xc0 [20699.107462] [<ffffffff810d17d0>] ? irq_thread_fn+0x50/0x50 [20699.107464] [<ffffffff810d174f>] irq_thread+0x1af/0x1e0 [20699.107466] [<ffffffff810d15a0>] ? irq_finalize_oneshot+0x120/0x120 [20699.107470] [<ffffffff8108566c>] kthread+0x8c/0xa0 [20699.107474] [<ffffffff815def34>] kernel_thread_helper+0x4/0x10 [20699.107477] [<ffffffff810855e0>] ? kthread_worker_fn+0x190/0x190 [20699.107480] [<ffffffff815def30>] ? gs_change+0x13/0x13 [20699.107481] handlers: [20699.107484] [<ffffffff810d0d90>] irq_default_primary_handler threaded [<ffffffffa00a9d10>] ahci_interrupt [20699.107496] [<ffffffff810d0d90>] irq_default_primary_handler threaded [<ffffffffa0cd2a40>] snd_hdsp_interrupt [20699.107501] Disabling IRQ #16 since the old report on lkml did not involve ahci, it is probably related to the threadirqs, isn't it? shall i report it on lkml or is there a better list to avoid that the report won't get lost in the noise? tim -- 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
