Do you have a printer? Try to boot while it is powered off.
WHAT is generating irq 7 now?

It is documented that interrupt controller will report irq 7 if it sees irq
but cannot determine what device sends it. That's exactly what's happening
when you see "spurious int" message.

You made kernel believe it's from printer. That does not cure the real
problem. BTW, there's not much of a problem, kernel just ignores spurious
interrupts. It _is_ a problem if you see 'ERR' number rapidly increasing.
