Comment 3 for bug 93019

Here's a bit more info.

The system doesn't become completely unresponsive immediately. It starts with only program that access the network being unresponsive and then everything. When I try to log off and restart it will stop at a blank screen until I ctrl+alt+backspace and the only way to start shutdown is to ctrl+alt+del before the x server has a chance to start again.After it that it stop most often at shutting down my vmware networks and will usually stay there indefinately. I usually just ctrl+alt+prntscr+s then ctrl+alt+prntscr+b. I still usually have to do fsck manually after it finds that my root partition isn't clean. None of this happened until I upgraded from Edgy.
