Re: 2.6.0-test3-mm3 reserve IRQ for isapnp (2.6.0-test3-mm3 <sigh>)

Hi,

Thanks, but it didn't work.  Right after mounting root, it locked up 
when activating a USB device...probably some sort of IRQ problem still.

If I could just force it not to take 3, 4 ,5 , and 7 for PCI, I'm sure 
it would work.
