Priority: medium Bug ID: 68585 Assignee: dri-devel@lists.freedesktop.org Summary: Recent Mesa git make Kwin crash with AMD R300g driver Severity: normal Classification: Unclassified OS: Linux (All) Reporter: rvdb@cryptolab.net Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r300 Product: Mesa

Created attachment 84671 --> https://bugs.freedesktop.org/attachment.cgi?id=84671&action=edit Kwin backtrace

I run Slackware64-current systems on several workstations using AMD processors and graphic cards. I usually compile my own very recent kernels (currently 3.11-rc*) and I regularly (about once every two weeks) compile git version of libdrm, mesa and xf86-video-ati. I noticed that with recent versions of mesa, kwin, KDE's compositor and windows manager, crashed immediately at boot and only worked when I disabled the OpenGL effects. The last version of mesa that worked was of the 2013/08/08. By just changing mesa to a more recent version, kwin would segfault, for the first time in years, with KDE 4.10.5 as well as 4.11. My other systems, which have a fairly similar OS settings, do not have these issues but they use the r600g driver while my old laptop, the one which crash, still use r300g. I've attached to this kwin backtrace which clearly shows that kwin crash while working with r300_dri.so, as well as the startx output. I don't have debug binaries unfortunately.
