I saw similar problems when I started using the later AIC7xxx drivers. I
suspect that the problem has to do with the handling of external
devices. On my HP Vectra XU, the BIOS has a setting that disables ultra
(20 MB/sec) transfers when any devices are attached to the external
68-pin connector. I believe that recent AIC7xxx continue to try to
transfer an 20MB/sec even when the BIOS is so configured and such
external devices are attached (despite the fact that the total cable
length may be 7 feet or more). I solved this problem by taking a surplus
AVA1505 out of the closet and attaching some of the external devices to
that controller; those who don't have such a well stocked closet may not
be able to get around the problem that way...
