ACPI interrupt woes

[Derek Tattersall]

Isearched for the following in the current and hacker archives but I
didn't find a match.

>From a CURRENT kernel built today, I get:
Interrupt storm detected on "IRQ15": ata1; throttling interrupt source
acd0: WARNING - MODE_SENSE_BIG interrupt was seen but taskqueue stalled

This is on an ASUS A7V600 board at latest BIOS level with Athlon XP
2800+ and 512 MB of memory.

A CURRENT kernel from April 8 boots just splendidly.

The May 5 kernel will boot with ACPI off.

Can anyone explain what's going on here, and offer perhaps a hint for a
fix.
