Just thought I'd provide a heads up on a trange thing that happened this 
evening ...

I decided to put a 312MB Micropolis ESDI onto the other LUN of my 
MD/21.  I partitioned it up, and decided to move /usr over there...when 
doing the tar, it wedged ... disk wait.  I recompiled the kernel with 
reselects disabled and was working fine.  Now, I jut got a:

ncr5380_command: short transfer: wanted 10 got 6
si(0:0:0)-28,0,0,3,b1,0,0,0,10,0-

Twice.  On the same file.  Once copying it to the other disk (which is 
si(0:0:1)) and again comparing them.  This results in a "soft error" 
message later, which I did see from time to time with the old driver, so 
I'm guessing it's probably a bad block...happily enough, the file (gdb) 
compares fine.  Dunno ... kinda weird, though.  Worth noting, installing 
gdb with the new driver before the last round of changes was fine ... 
I'll see about the latest one, which is what I'm using now.

In any case, I thought I post this in case anyone had any ideas...here's 
what dmesg(8) says, adjusted to fit 80 columns:
