Some additional observarions:
On my most recent boot things seemed normal for awhile with both top
and xperfmon++-3.0 behaving normally. However, while reading some mail
via mutt I scrolled to the bottom of the mail item and got several
beeps (as I tried to go further). At that point the tty out chars/sec
on xperfmon++ jumped to over 210,000 and the interrupts went to over
37,000/sec. At the same time Idle CPU % went to zero. Soon xperfmon++
crashed. Upon restarting xperfmon++ I see that I am still getting over
55,000 tty out chars/sec and over 40,000 interrupts/sec. Letting the
system idle for several minutes still has the tty out char/sec in the
20,000/sec range and the interrupt/sec at about 17,000.
Something does seem really strange.
Thanks,
Bob
