I spoke too soon. The increased DELAY allowed me to survive
a make world, but some subsequent knews/leafnode/X activity hosed
things again :-( The second time this happened, I did see a
ata0: unwanted interrupt 1 status = 50
message on the console....
BTW, I'm running softupdates on a single monster partition:
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/wd0s1a 3671854 2912919 465187 86% /
procfs 4 4 0 100% /proc
kernfs 1 1 0 100% /kern
but I don't think this is relevant (unless I'm experiencing more than
one problem).
