Hello Gentlemen,
for three times during the past few month now, my iBook (500 MHz G3,
640 MB RAM, Mac OS X 10.4.2) all of a sudden stopped doing anything.
Yesterday, it was in midst of reading my daily eMail dosage: The
cursor continued to move around, but other than that, everything
appeared to be deaf. The cursor's shape didn't change according to
the underlying window anymore, keystrokes had no effect, clicks won't
do anything and even when closing the lid, the computer would (at
least partially) stay awake. I always waited some time to rule out
processor overload.
The reason why I'm writing this to the kernel list is, as soon as I
unplugged the ethernet cable, the machine became responsive again.
The keystrokes pressed while the computer was in "deaf mode" were
executed and the computer appeared healthy as ever within a single
second. It then fell into sleep as it should have done five minutes
before, and could be awoken normally.
So my question is, how would one attack this kind of bug? Should I
install an instrumented kernel? Should I try to connect to the
machine via ssh? Should I run some background task to get more
information?
Thanks,
Markus
P.S.: This is system.log's contents for the time frame in question:
