Hi,
Just migrated to 2.6.10 on an old VIA MVP3 box and I'm getting this:
irq 12: nobody cared!
[<c012bb42>] __report_bad_irq+0x22/0x80
[<c012bc0c>] note_interrupt+0x4c/0x80
[<c012b6f8>] __do_IRQ+0x118/0x140
[<c0103d76>] do_IRQ+0x36/0x60
=======================
[<c010271a>] common_interrupt+0x1a/0x20
[<c0117730>] __do_softirq+0x30/0xa0
[<c0103e79>] do_softirq+0x39/0x40
=======================
[<c012b574>] irq_exit+0x34/0x40
[<c0103d7d>] do_IRQ+0x3d/0x60
[<c010271a>] common_interrupt+0x1a/0x20
[<c012b914>] setup_irq+0x94/0x120
[<c01f20a0>] i8042_interrupt+0x0/0x180
[<c012baf2>] request_irq+0x72/0xa0
[<c03ab9a1>] i8042_check_aux+0x21/0x140
[<c01f20a0>] i8042_interrupt+0x0/0x180
[<c03abe78>] i8042_init+0xf8/0x180
[<c039c80b>] do_initcalls+0x2b/0xc0
[<c0100440>] init+0x0/0xe0
[<c0100467>] init+0x27/0xe0
[<c010084d>] kernel_thread_helper+0x5/0x18
handlers:
[<c01f20a0>] (i8042_interrupt+0x0/0x180)
Disabling IRQ #12
Once the system is running, /proc/interrupts shows
CPU0
0: 1073809 XT-PIC timer
1: 1291 XT-PIC i8042
2: 0 XT-PIC cascade
4: 7 XT-PIC serial
5: 4366 XT-PIC eth0
7: 12 XT-PIC parport0
8: 1 XT-PIC rtc
10: 7698 XT-PIC uhci_hcd, uhci_hcd, eth1
11: 58320 XT-PIC ide2, ide3
12: 306731 XT-PIC wifi0
14: 24446 XT-PIC ide0
15: 13 XT-PIC ide1
NMI: 0
ERR: 0
that IRQ 12 is a wireless device:
0000:00:09.0 Network controller: Intersil Corporation Prism 2.5 Wavelan
chipset (rev 01)
that gets handled by HostAP. The device is operating correctly.
What's to blame here?
Thanks,
