Comment 40 for bug 138094

Ditto for me. I have an Athlon 64 3400+ with a Radeon 9800 Pro video card using xorg drivers. The crash seems to occur randomly... I have Compiz enabled with several effects, and have been sleeping/resuming my machine as well. The GUI will sometimes report "an error occurred while putting this computer into sleep mode", but I can't find any evidence in the logs (dmesg, /var/log/messages, kern.log). Any ideas as to what might be causing this?
