Spurious 8259A interrupt: IRQ7
From LinuxNewbie

Q: I keep on seeing "spurious 8259A interrupt: IRQ7." in my logs. Help! A: The IRQ7 message is a common problem ... All that's happening is the kernel has received an interrupt from the parallel port but hasn't got a parallel port driver to deal with it. It's not a problem, the kernel will just ignore the interrupt anyway. Feel free to do the same.
Solutions:
Install a parallel port driver in your kernel.
Disable the parallel port in your BIOS.
