The problems had disapeared if I set
options aic7xxx aic7xxx=noapic
in the /etc/conf.modules

Betreff: timeout problems w/ AHA-2940U2 and linux driver 5.1.19
Hello,
I'm experiencing lots of timeouts and bus resets with an AHA-2940U2
and Linux' aic7xxx.c 5.1.19. Performance is severely affected, but the
machine does stay running.
The machine is a Micron Client Pro, running kernel 2.2.12. Termination is
enabled on both busses. (Not automatic mode.)
If I can provide any more information than the following, or run any
tests, please don't hesitate to ask.
