I'm very surprised to find out that maybe I'm not alone in the universe. I
have a 6.3-PRERELEASE system (last cvsupped Dec 12), which always freezes
*once* a few minutes after booting up. This happens typically at the time
when I've just logged in using xdm, fluxbox has started up and I'm opening
my first xterm. The freeze lasts approximately 1-3 seconds. Once this
freeze is over, it doesn't happen again until I shut down the machine for
the night. But it does happen every time after starting up.

I have xorg 7.3. I don't have the full Gnome installed, but I do have gtk
2.12 and lots of other gtk-based "stuff" from gnome 2.20

Mine gets shut down every night.

Intel D865GLC mobo (i865), 2.8 GHz P4, 768 MB DDR, integrated i865
graphics, integrated Intel Pro/100 Ethernet, additional VIA Fire II
(VT6306) PCI FireWire adapter, 1x80 GB ATA disk. Arbitrary PCI
SoundBlaster workalike which calls itself "AudioPCI ES1373-B".

I've always just thought it to be some random hardware glitch that is
hopeless to track down, but maybe I'm wrong. This machine was installed
with FreeBSD just last autumn and initially it didn't have this problem
running 6.2-STABLE. Unfortunately I can't pinpoint which source update or
ports update or any other change it was that triggered this behaviour.
