<pre>I have now two consecutive reboot : I describe.
1. I worked on Iceweasel 24.8.0 with two opened windows. One editing a SPIP
site.
The second with editing a Wikipedia article, more one other tab with Wikipedia.
Claws-mail was also opened.
2. A reboot occurred without any log.
3. The system reboots on 3.16.1 kernel with always radeon.dpm=1.
4. I reopened a session on Xfce.
5. I rerun Iceweasel only. All the tab and windows are restored.
6. I opened this bug report and begun this new comments.
7. After writing two or three lines in the text area, the system rebooted
again!
8. I replaced radeon.dpm=1 with radeon.dpm=0, rerun update-grub.I rebooted.
9. I rerun again Iceweasel with restored tabs and I can now fill this comment !
To conclude. The reboot problem is not fixed by a radeon.dpm=1 in grub. So the
summary of this bug is not exact. I expect that no new reboot happened again.
I'll follow with dpm=0 to see.
Note that about 2 two seconds before a reboot, xorg freezes (a watchdog effect
?).
I have also a little doubt with a kernel network side-effect.
My question : how get a debug log when an immediate reboot happened?</pre>
