next in thread | raw e-mail | index | archive | help
With nothing special going on (I think maybe a tar xfvz of the jdk 1.2.2
source), my system crashed inexplicably. I have no idea why a lock would
look like this does, no clue whether I should be replacing my hardware or
the system is just getting more and more unstable.
