Re: Intel 82801H SATA interrupt issues

[Brian Buhrow <buhrow%nfbcal.org@localhost>]

	hello.  Can you tell which device is generating the interrupts and where the interrupts
are being routed?  When I've seen things like this in the past, I've found the issue is often
that the interrupts aren't getting to the right driver, or they're going to no driver, which
creates a lot of CPU overhead.  Are you geting missed interrupt messages from the kernel for
the SATA chips?
That's a sign interrupt routing is an issue.  Just out of curiosity, what happens if you boot
with ACPI disabled on this machine?
