It seems this is a recurring issue, see #855199. The problem is that the
irqfixup code gets broken. There is of course an underlying problem of
spurious interrupts but booting with the irqpoll option should handle
this. It worked for awhile but seem to have reoccured from at least
kernel 3.2.0-39 in precise, possibly earlier.
I am now running quantal 3.5.0-27 and the problem remains. If the wrong IRQ
gets disabled the system gets sluggish and needs rebooting. It is extremely
frustrating. I am running an AMD Fusion board:
Example dmesg output:
