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. -- vda - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
