It is me again.
After applying the latest patch kit for 4.0F onto our 4100 5/400
(PK3, just uploaded to the dec patches site on Friday...), I had
hoped that our problems were over. To refresh your memory, we were
having intermittant "buffering" of keystrokes -- they seem to
occur in all windows - with all logins - at the same time(s).
After a few seconds, everything a user had typed in a given window,
showed up correctly in that window... This started last Wednesday
morning (March 8) and led to a system crash that same afternoon.
dia and uerf reported
panic (cpu 2): simple_lock: time limit exceeded
Despite my best efforts and the wonderful help (I learned a lot!) of
this group, I was unable to figure out exactly what happened, but the
behavior improved (fewer instances of the "buffering") and then the
new patch kit came out -- with several patches mentioning simple_lock...
With High Hopes, I installed the kit on Saturday. Unfortunately, the
behavior is still there -- not very often, but still.
Today, I noticed the following in the dia output and wondered if it means
one of our CPUs is going bad:
