after having thought about this a little bit, I would like to write down as much information as I can.
I wrote "randomly" because it really is randomly. This means, the user can not determine a reason for these reboots. There is no obvious connection between something the user does and the occurence of these nasty reboots. This means, that the system could be running for 10 minutes (this was the maximum, I managed) or just a few seconds. Sometimes even at Bootup the system started over. In my maximum uptime of 10 minutes, I tried to install the fglrx-updates package via this "additional drivers" menu. It downloaded the package and installed - and even during the install of this package, when the system was busy doing something (I was moving the mouse....) it rebooted, leaving a broken system, because fglrx was not installed completely. These reboots also happen during install of the system (no previous operating system present). Mostly it booted up to the menu, where you can choose to try Ubuntu first or install directly. It showed this menu and in the next moment, it shut down. In Bugreport no. 1309578 somebody mentioned in the comments, that moving the mouse constantly does the trick to keep the system running until fglrx is installed. I also tried this, but I don't think that this really makes a difference because the system was also shutting down some times, even as I moved the mouse constantly. I installed the system via Ubuntu 12.04.4 because I did not realise that some bootoption (radeon.dpm=0) also would do it. But I noticed that 12.04.4 started the Live environment much faster than 14.04. Also after install, the system booted much faster and as I mentioned already, it did not have the reboot-issue with the radeon driver. At least I did not experience it. Now, 14.04.1 is running flawless with fglrx-updates installed. I am not really sure, whether this report is helpful because all the data is collected with fglrx-updates installed. But using the radeon driver really makes the system unuseable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1372169 Title: random reboot with MSI A78M-E45 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1372169/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
