I had a similar symptom when I ran dhclient to get an ip address when I 
had one of the problematic 3 com cards that used to work properly.

KDE is not so touchy with a properly working ethernet connection. 
Mozilla and GNOME really get a bit touchy when the connection is not as 
it should be.

I would try to not enable your nic during boot. Then once booted up, try 
to log into GNOME. I was able to do so, with the similar problem to yours.

Then try to launch mozilla and see if it works on your machine, not an 
internet site. If you can do this, bugzilla the NIC with the make/model 

If you start GNOME, then get an IP from dhclient or whatever means, you 
probably won't be able to logout of GNOME. Mozilla probably wil start, 
but not allow you to type anything into the location bar.

I submitted bugs during tests for Fedora on these sort of symptoms.

Also, instead of letting the machine die totally, which will ask for a 
disk check, try poweroff or as root telinit 6.

I have a problem related to reiserfs with the 2.6 kernels and use the 
telinit 6 to shut down. It works alright, even with big problems. You 
still might need to hit the powerswitch to reboot, but it will shut down 
most processes.
