I'm seeing the same problem here under heavy load. System is an HP Vectra XU
6/150 SMP with onboard aic7880U (Rev 0), BIOS 1.2v-HP.
When I originally tried 5.1.* AIC7XXX drivers, I was unable to boot due to
parity errors. I fooled around with cables, termination and the driver
termination settings without success. I finally dug an old AVA1505E out of the

runs ok under light
load but I get timeouts under heavy load. With the old AIC7XXX drivers, the
system ran great.
