BIOS is fresh: a week ago release. Tried 3 > different versions. Try turning off various device drivers (like myk) to see if you can get the= =20 interrupt storm on IRQ 23 to go away. It is likely a bug in interrupt=20 routing in your BIOS, but you can use a tunable to work around it, you just= =20 need to figure out which _other_ PCI device (not atapci2) is sending its=20 interrupts to IRQ 23 rather than the IRQ the BIOS told the OS. =2D-=20 John Baldwin
