[wellylug] Debian Sarge Freezing on boot.

[lug]

Hi,

I'm running debian sarge. Ever since I did the recent dist-upgrade which
included the kde3.1 update (amongst many many things), my box has been
misbehaving. Every now and then it fails to boot, and freezes at either
one of two points in the boot process. The only thing that I can do is
cross fingers and power cycle until it decides it wants to be friends
again. 

Has anyone else seen anything like this? Let me know otherwise it looks
like I'll need to post up to the debian lists.

Cheers

Jamie
