Stefan & -hackers,
Awhile back I experienced some serious problems when I rebooted my
machine. It hasn't happened lately, although that may just be because I
haven't rebooted but once in the last 10 days. I promised some
documentation describing in detail what was going on, so here it is.
Here's what happens when I boot the machine. For completeness' sake,
I've included just about everything I see on the screen (I had to
reboot the damn thing a half a dozen times to make sure I got 'em all!:)
This problem *is* repeatable, but doesn't happen every time I reboot
the machine! I have *no* idea what triggers it.
