I haven't seen any kernel-related commits since I did the CVSup (from
0347 - about 0356 hrs. today, US/Pacific (8 hrs. west of GMT).
(Previous CVSup was 24 hrs. earilier, and the kernel built then -- which
is what I was running when I built this one -- had not exhibited the
symptom.)
Anything else I can do to help find & resolve this?
Thanks,
david
