Public bug reported: Hi,
after plugging in an USB device, it doesn't get noticed until I say lsusb in terminal - then it activates properly. Maybe it is related to what I get in dmesg (complete output attached): [ 28.399792] irq 18: nobody cared (try booting with the "irqpoll" option) [ 28.399946] [<c0160934>] __report_bad_irq+0x24/0x80 [ 28.400108] [<c0160c0b>] note_interrupt+0x27b/0x2c0 [ 28.400272] [<f887ab8b>] usb_hcd_irq+0x2b/0x60 [usbcore] [ 28.400455] [<c015fe30>] handle_IRQ_event+0x30/0x60 [ 28.400612] [<c01615a6>] handle_fasteoi_irq+0x86/0xe0 [ 28.400767] [<c0107ecb>] do_IRQ+0x3b/0x70 [ 28.400924] [<c0132b51>] irq_exit+0x51/0x80 [ 28.401079] [<c0119885>] smp_apic_timer_interrupt+0x55/0x80 [ 28.401240] [<c01063f3>] common_interrupt+0x23/0x30 [ 28.401405] [<c020f487>] delay_tsc+0x27/0x50 [ 28.401561] [<c020f426>] __delay+0x6/0x10 [ 28.401719] [<f88e47dd>] ohci1394_pci_probe+0x2dd/0x690 [ohci1394] [ 28.401885] [<c021c373>] pci_match_device+0x13/0xc0 [ 28.402042] [<c021c516>] pci_device_probe+0x56/0x80 [ 28.402199] [<c0275878>] driver_probe_device+0x88/0x190 [ 28.402366] [<c0275aee>] __driver_attach+0x9e/0xa0 [ 28.402521] [<c0274cab>] bus_for_each_dev+0x3b/0x60 [ 28.402682] [<c02756f6>] driver_attach+0x16/0x20 [ 28.402844] [<c0275a50>] __driver_attach+0x0/0xa0 [ 28.403005] [<c027502a>] bus_add_driver+0x8a/0x1e0 [ 28.403161] [<c021c6c6>] __pci_register_driver+0x56/0x90 [ 28.403321] [<c0151296>] sys_init_module+0x126/0x19c0 [ 28.403483] [<c020cef7>] rb_insert_color+0xb7/0xe0 [ 28.403641] [<f8927270>] hpsb_bus_reset+0x0/0x100 [ieee1394] [ 28.403814] [<c0105422>] syscall_call+0x7/0xb [ 28.403974] ======================= [ 28.404059] handlers: [ 28.404136] [<f887ab60>] (usb_hcd_irq+0x0/0x60 [usbcore]) [ 28.404369] Disabling IRQ #18 I tried booting with the irqpoll option, the oops didn't show up in dmesg and hotplugging worked, but integrated trackpoint motion was very sloppy (as if processed only 10x/second or so).
