1. Gnome starts new session out of the blue<br>
<br>
Today I was editing a document in gedit. Other open applications were<br>
chromium-browser and gkrellm. Suddenly out of the blue in the middle<br>
of writing a word the screen changed to a new session, screen with GDM<br>
showing). Logging in again no application was saved, work lost as well<br>
as 2 tabs in the browser where I did not save the URLs yet. syslog<br>
shows a Gnome session I/O failure before the session switch:<br>
<br>
- Jul 6 07:28:49 marvin-1 gnome-session[2301]: Gdk-WARNING:<br>
gnome-session: Fatal IO error 11 (ressource temporarily not available)<br>
on X server :0.<br>
<br>
After session restart a long list of "DEBUG" messages followed. No<br>
errors reported in that list.<br></blockquote><div><br>For this part of your problem, I guess you are hitting this bug:<br><br><a href="https://bugs.mageia.org/show_bug.cgi?id=2585">https://bugs.mageia.org/show_bug.cgi?id=2585</a><br>

2. Occasional system deep freeze<br>
<br>
Starting some time ago and occurring last time yesterday I get a deep<br>
freeze (only SysRq keys for forced reboot working). Inquiring I found<br>
this message in syslog:<br>
<br>
- Jul 5 13:27:42 marvin-1 kernel: [10565.322087] NVRM: GPU at<br>
0000:01:00.0 has fallen off the bus.<br>
<br>
man-draker in the German forum pointed me to<br>
<a href="http://www.cyberciti.biz/faq/debian-ubuntu-rhel-fedora-linux-nvidia-nvrm-gpu-fallen-off-bus/" target="_blank">http://www.cyberciti.biz/faq/debian-ubuntu-rhel-fedora-linux-nvidia-nvrm-gpu-fallen-off-bus/</a><br>
which talks about persistence mode of nvidia-smi. The persistence mode<br>
is disabled by default. Switched it to "enabled" but I am not sure if<br>
this is the true culprit - the same error should have come up more<br>
often and on other people's machines as well if this setting was the<br>
culprit, right?<br>
<br>
Another idea was offered by doktor5000:<br>
"It could be some malfunction of systemd and you could ask Colin about it". :)<br>
<br>
Additional information: the freeze is not caused by faulty memory, I<br>
let memtest run over nicht for 8 hours, no errors.<br>
