'Xorg panic' - ubuntu freezes

[inzaghi89]

Hi. I've got ubuntu 8.04.1, and it really like made for me system freezes. Only hard restart can help me (i mean: alt+sysrq+s,u,b - [...]+k don't work). This is my warning log (i think ):

How can i fix this problem? It's really clear version, because has only one day... So it's impossible to made something wrong and crash the system myself.

[ram130]

are you running it from the live cd?

[inzaghi89]

I've installed ubuntu from livecd, but it's installed version on hard drive.

So, could somebody help me? What should i do to fix that "feature"?

hmm interesting it is I get this just before a freeze as well "NetworkManager: <WARN> nm_dbus_get_networks_cb(): error received: org.freedesktop.NetworkManagerInfo.NoNetworks - There are no wireless networks stored.. "
This looks like a nice bug in networkmanager!
