Here is a workaround that seems to fix problems with kmem panics and
hangs while doing NFS... (it has worked for at least one other person)
mount using the options "-o rsize=4096,wsize=4096" (the defaults are 8192.)
Since doing this, we have not seen another panic! As a side effect, NFS
seems to run faster!
This is our best guess, description of our system:
a generic clone 80386 motherboard with an AMI MK-II AT BIOS,
8 meg of memory, 80387, Twinhead EGA card, WD1007A disk controller
with 2 CDC Wren III ESDI drives, and a 3com Etherlink II card.
This is a list of patches we have applied:
original 2nd drive patch
MAX_KMAPENT increase patch
bufpages = min(NKMEMCLUSTERS/2, bufpages) patch
npx 0xf1 -> 0xb1 patch
