[2.6.9] irq 19: nobody cared

[2.6.9] irq 19: nobody cared

[Bernd Schubert]

Hello,

I already got this several times, any ideas whats causing it? I have disabled 
apic for now in the bios, which makes usb and sound to share the interrupt:

11:      11507          XT-PIC  Ensoniq AudioPCI, uhci_hcd, uhci_hcd

As far as I remember, with enabled apic irq 19 is only used by the soundcard, 
if this might be interesting, I can look this up later on.

Here the oops with enabled APIC:
