So I replaced the line "--enable-glx-tls" with "--disable-glx-tls". However, the GPU lock ups still happen and I can't start X. Then I tried setting several environment variables like it was suggested in yet another bug report (https://bugs.freedesktop.org/show_bug.cgi?id=69728): Neither R600_DEBUG=nohyperz, R600_DEBUG=nodma, R600_DEBUG=nosb or R600_LLVM=0 did help. Not alone and not combined. Additionally, I removed the lines "--with-llvm-shared-libs" and "--enable-gallium-llvm" from the ./configure parameters, because I read in bug 69728 there might be some issues with LLVM. This also didn't change anything (the binaries got obisously much bigger, though). The next thing I wanted to try is to disable "the new DMA ring for ttm bo moves" like suggested by you (Alex) in another thread about GPU lockups (https://groups.google.com/forum/#!topic/fa.linux.kernel/1_KzqknQn_U). However, this change seems to be already in the mainline kernel. -- You are receiving this mail because: You are watching the assignee of the bug.
