[Jon "The Nice Guy" Spriggs]

This issue occurred having installed the Maverick Netbook image, performed an apt-get update && apt-get dist-upgrade today at approx 7:15PM BST and then opened three separate applications, Empathy, gnome-console and firefox. Task swapping between these firefox and gnome-console seemed to have caused this crash.

Seems to be a prevalent issue with netbook remix and asus netbooks, but have not researched enough to see if it is that specific.

[shoo_ash (ash-mail)]

Not only netbook remix. I've got

on eeepc 900ha with normal desktop install and live system after each boot.

That also affects me at Asus EEPC 1008ha.
And keeps after 15/09/2010 kernel update
