Although IRQ7 is traditionally LP, it seems to get identified for almost 
any unexpected interrupt. I knew why once, but I haven't seen this for 
some time. The real problem is that the kernel disables the IRQ, making 
the system unusable. You can try any of several things:
- try the last 2.6.16 kernel
- remove the IRQ disable code, or add a counter. It happens only once on 
many machines,
  as something comes ready.
- switch to IRQ poll
- disable any CPU speed stuff you have running (just for information)
- try the question on a Fedora list, or report as a bug
- look for newer BIOS formware

Yes, that's a shotgun approach, I'm still running 2.6.16.2111 on FC4 
because later kernels don't init the video or wireless correctly.
