I just supped and created a new kernel. I still have the problem.

The disk is a Quantum 270A (IDE)

Geometry (according to the manufacturer and the boot message)
   944 cyl (800 according to disklabel -i)
   14 head
   40 sec

I created the latest disklabel with -i so the partition table reads:

rpm: 3600
interleave: 1

#   size offset fstype  fsize bsize cpg  
a  32480   0    4.2BSD  1024  8192  16  # (cycl 0-57)
b  32480 32480  swap                    # (cycl 58-115)
c,d unused
h 382480 64960  4.2BSD  1024  8192  16  # (cycl 116-798)

Previously the disk had Win 3.11 installed (and was reputed to work well),
I personally did not work with the system.
