The most recent (as of about 1000 EST 2/26/97) kernel seems to be extremely
fragile; it takes very little disk activity on my ASUS P5-120/64 MB RAM to
cause a panic (4 in the past 2 hours).  I know -current is dangerous to run
and being worked on, and I'm not complaining, I'm just sending this on the
chance it may be useful to someone...
