That doesn't seem to affect me.

Well, one thing I _am_ seeing in addition to this, is thousands of
interrupts per second from EATA DMA SCSI.

This is with no disk activity.

% (cat /proc/interrupts ; sleep 1 ; cat /proc/interrupts) | grep eata
11: 394173123 394165656 IO-APIC-level eata_dma
11: 394185079 394177612 IO-APIC-level eata_dma

That is roughly 20K interrupts in a second!

Before with 2.1.124 this did not happen, but I switched to Mike
Neuffer's DPT SCSI driver and now it does even here.

So with Dario's SCSI driver, 2.1.124 is fine, but adding Alan's
ac1 patch causes the mouse to go nuts.

2.1.124-2.1.126 with Neuffer's driver also causes the same behavior.

I don't believe I got interrupt storms in eata_dma with just Alan's
patches to 2.1.124.
