AIC 7890/1 Ultra 2 under Linux

[Dirk Lutzebaeck]

Gero, you are the third here on the list who has stated timeout
problems with an ASUS P2B with onboard 7890 controller (I'll rule out
termination problems for time here). In all three cases there are
devices attached to the SE-Bus. It seems that these devices
occasionally completly lock the bus. Does your problem appear when
using the CDROM-devices? I'll suspect the Adaptec BIOS on the ASUS
P2B-D/S. What is your version number?
