What you are experiencing is hitting a bad sector in your swap space.
This happened to me and the only way I've been able to get around it
for now was to move my swap space somewhere that didn't have bad sectors.
If you've been following the discussion on bad sectors on EDSI drives
there was method of discovering where you have bad sectors by doing
a dd if=/dev/wd0c of=/dev/null bs=512 conv=syn,noerror. Grab a copy
of the unofficial FAQ (I think it's on agate), there is a good set of
instructions on how to install 386BSD manually, reinstall your system
with your swap space in a clean section of disk, leaving a gap between
probably your root partition and your swap partition (this is where the
bad sector is). I was fortunate in that the bad sector on my drive
was close enough to the start of swap that I was able to relabel my
disk shrinking swap a little and leaving a gap where the bad sector was.
Another apprach people are having success with, if your controller
supports it, is to enable alternate sector mapping and do a new low
level format of your drive, this should make the drive to appear
defect free to 386BSD.
This whole bad sector issue seems to be a problem for a lot of people,
lets try to coordinate the effort and get this working. Keep those
posts coming with any and all ideas and efforts!
