IRQ handler type mismatch for IRQ 7

[Vegard Nossum]

Hello,

I receive this on a fresh install of Fedora 7 (x86_64) running
2.6.21-1.3194.fc7, and wonder if it's something to worry about:

IRQ handler type mismatch for IRQ 7
current handler: parport0

Call Trace:

The machine still runs, though X.org crashes with SIGSEGV. I have a
feeling the two are unrelated. The full dmesg follows.

Kind regards,
Vegard Nossum
