>Environment:
NetBSD 1.5 (GENERIC) on VAXstation 3100/m30, 24MB RAM, 1GB IBM disk
on scsia and 4GB quantum disk on scsib (external).

>Description:
After having upgraded my VAXstation from 1.4 to 1.5 (actually reinstalled)
and hooked on an external scsi disk to the second scsi bus, I have seen
some soft errors on sd0 and now a severe crash with the following output
with sd1:

 The disks are known to work and the internal disk (sd0) has worked
 without any problems for over a year in the VAXstation.
 Since I remember the scsi problems with the second disk in 1.5_ALPHA
 I thought maybe there're still some bugs lurking in the DMA code
 concerning the second scsi bus on the VAXstation?
