[Xen-devel] "irq 19: nobody cared!"

[Nicholas Lee <emptysands@xxxxxxxxx>]

I've been getting this error regularly during the last week while
compiling and trying to get Xen 3.0.  Possibly related to system load.

IRQ 19 is USB, which is not used on this system. Standard PS2 keyboard
and mouse.

Its likely I'll disable USB for this system anyway, particularly once
I've set up the ipmi console.
