2.6.10: irq 12 nobody cared!

[Joshua Kwan]

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

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

  7:         12          XT-PIC  parport0
  8:          1          XT-PIC  rtc
 10:       7698          XT-PIC  uhci_hcd, uhci_hcd, eth1

 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,
