Ping?

Any other suggestions? In the week end I try to patch the SATA driver
and USB driver.

I add some debug print from UHCI interrupt handler. So the interrupt
start to hammer as soon as the first UHCI hook to IRQ 19. The UHCI
status bit is clean.

I also try to disable SATA interrupt at early PCI scan. It does not
help either.

So I guess seems like wrong irq routing. How do I find out which
device is injecting the interrupt?
