Darrick,

It's the mfgpt-timer that is already using interrupt 7.

I had a similar issue myself with a PCI card.

To fix this you can change the default irq for mfgpt-timer
in x86/kernel/mfgpt_32.c:

at the top, change:

#define MFGPT_DEFAULT_IRQ       7

to:

#define MFGPT_DEFAULT_IRQ       <unused interrupt>( I chose 6)
