This file is xorg.log taken after the bug occured and the GUI was completely locked up.
I can't find any relevant error messages, but I am including it just in case. ** Attachment added: "Xorg.0.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1507150/+attachment/4497946/+files/Xorg.0.log -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1507150 Title: [all variants] - Radeon HD3650 - radeon.dpm=1 - ring 0 stalled for more than 10 Status in linux package in Ubuntu: Confirmed Bug description: When the screen saver is left running for a few minutes, the computer locks up. 1 out of 2 times, I have to do a hard reset ( hold power button for 30 seconds or disconnect power/battery. ) 1 out of 4 times, I can reset the computer using the magic sysrq ( Raising elephants... ) 1 out of 4 times, I can switch to a console ( CTRL+ALT+F1 ). The GUI can not be recovered, it remains frozen. The last time I managed to switch to a console, I managed to capture dmesg and xorg. Messages like this are seen in dmesg after it has locked up: [ 2077.860355] radeon 0000:01:00.0: ring 0 stalled for more than 12488msec [ 2077.860371] radeon 0000:01:00.0: GPU lockup (current fence id 0x00000000000184c0 last fence id 0x000000000001864c on ring 0) [ 2077.860997] [drm:r600_ib_test [radeon]] *ERROR* radeon: fence wait failed (-35). [ 2077.861067] [drm:radeon_ib_ring_tests [radeon]] *ERROR* radeon: failed testing IB on GFX ring (-35). Notes : This problem is easily reproducible on a HP 8530p with a n [AMD/ATI] RV635/M86 [Mobility Radeon HD 3650]. This bug affects all versions of Ubuntu/Kubuntu/Ubuntu-mate/Xubuntu since Ubuntu 11.04. On Ubuntu 10.04, the issue does not occur because I can use the non- open source fglrx-legacy driver. When using the open source 'radeon' kernel module to run the Mobility HD 3650 device, the driver locks up frequently. The behaviour varies slightly from version to version, but the following description will be the behaviour in Ubuntu-Mate 15.04. The issue only occurs when 'radeon.dpm=1' is passed as a kernel parameter. This option is needed otherwise the card runs really hot and drains my laptop battery and burns my legs if the laptop is on my legs. It's not a hardware issue, it's a driver issue. Why? Because I tested using Ubuntu 10.04 + Legacy FGLRX, and the graphics card works fine without issue. I patched together Linux 3.4 + Xorg 6.9 ( xserver 1.12 ) + Arch Linux + Legacy FGLRX, and everything else modern, and the graphics card itself had no issues ( the installation was unstable because recent version of mate doesn't work well with old version of Xorg ) I strongly believe that it is a Kernel issue because the error messages all appear in dmesg. I can't find any errors in Xorg.lorg. A second, minor, issue that I have is that when I start the computer, the mouse can't click most places on the screen. When I click, nothing happens or the wrong thing is clicked. If I switch to a console and back to X, the issue resolves itself. This issue *might* be related to the main issue, but I do not have the technical skills to determine whether or not it is the same issue. My laptop runs with full disk encryption ( dm-crypt ). Notes about reproducing : I can reliably reproduce this. It can take up to 35 minutes to reproduce it sometimes, but I can reproduce it without fail. If you provide me with a test kernel to reproduce, please insure that dm-crypt is supported so that I don't have to reinstall the entire O/S.
