Otto,

I'm afraid that you're out of luck with the combination kernel 2.4.x / 
Buslogic adapter / HP scanner. The Buslogic driver doesn't properly 
handle data overruns/underruns in the 2.4 kernels -- but HP backend 
can't predict the precise length of the data returned for a certain SCSI 
  command, so data underruns or overruns can't be avoided.
