 This is always so.

 Booting interactively works always.

 When I choose we1 as the boot device, the error above occurs and 
 interrupts from we1 are handled (as well as exactly one from the 
 floppy).
 
 After that I can choose again...
 
 When I choose the defaults (md0a...) I reach the install menu and 
 everything is fine except that it can't find a hard disk to install 
 to, of course.
 
 Summary:
 When I boot interactively with flag "n", this always succeeds, 
 regardless if I choose "we1" or the default.
 When I choose the default, the install menu is reached.
 When I boot with flag "a", it hangs eternally as previously 
 described.
 Interrupts:
 When I don't try "we1", there are no interrupts from "we1" handled.
 When I try "we1" as a boot device, interrupts from this device are 
 handled.
 There is always one floppy interrupt handled.
