This isn't a gnome-session issue. It sounds like Xorg or the kernel is freezing. Tentatively reassigning to xorg-server for now.
Could you please do the following: 1. Please run "sudo lspci -vvnn > lspci.log" and attach the resulting file "lspci.log" to this bug report. 2. Please attach your /var/log/Xorg.0.log, /var/log/Xorg.0.log.old, /var/log/Xorg.20.log and /var/log/Xorg.20.log.old files to this bug report (if they exist). 3. Please attach your /var/log/kern.log file to this bug report. 4. Please also attach your /var/log/syslog file.
