Two notes first : 1. Meanwhile I upgraded to Mesa 10.1.0. 2. The patch seemed to be already included in the drm-fixes-3.14 branch, so I just tested with the latest version of that branch. Now the tests themselves : 1. With dpm=0 and hyperz enabled, the drm-fixes-3.14 branch is stable. 2. With dpm=1 and hyperz enabled on Mesa 10.1, both the drm-fixes-3.14 and the vanilla 3.13 would freeze at boot (when loading the display manager, lightdm). 3. With dpm=1 and hyperz disabled, they would work for a while, but as initially described on this bug, after a while they freeze or lockup. The most secure way I found to trigger a freeze is to play a HD movie using the "gl" output of mplayer, with that, it freezes in a few minutes. @Mihai : I'm uploading my build of the drm-fixes branch (which I wrongly named drmnext, but it's really the drm-fixes branch... sorry, but I didn't rebuild it just to fix the name...) on http://kilobug.net/debian it's for Debian not for Ubuntu but it *should* work on Ubuntu too. -- You are receiving this mail because: You are watching the assignee of the bug.
