Can you get this to happen outside of X at all (eg if you do a yum update
and pull in packages over the modem for a while with 2.6.23-rc1  does it
die). Just trying to work out what has become unstable.

Also worth trying to see if browsing web type stuff off a CD or local
files triggers it without the network link.
