Bisection points to: commit bb635567291482a87e4cc46e6683419c1f365ddf Author: Jerome Glisse Date: Wed May 9 15:34:46 2012 +0200 drm/radeon: convert fence to uint64_t v4 Radeon graphics are still broken for me in both 3.5.2 (from linux-stable) and 3.6.3-rc3 - though the symptoms appear to be slightly different. I'm currently running a kernel built from the commit before the above, and everything seems sane and stable. I'm happy to do any tests you might find helpful.. == Symptoms When booting with above commit, grub works fine but immediately upon attempt to switch graphics mode a solid green bar appears across the screen. System does not respond to ctrl-alt-f2. Very repeatable. When booting with later releases (eg 3.5.2), the greeter screen is displayed - sometimes correctly, sometimes with minor graphics corruption. Immediately switching to a virtual terminal works. However any attempt to move the mouse or log in via the greeter screen causes graphics corruption and system no longer responds. Also consistently repeatable. == OS details: Ubuntu 12.04 32-bit (default kernel 3.2.0-29). == System details: HP/Compaq nc8430 laptop $glxinfo | grep renderer ==> OpenGL renderer string: Gallium 0.4 on ATI RV530 $ lsmod | grep radeon radeon 815703 3 ttm 71375 1 radeon drm_kms_helper 32563 1 radeon drm 220833 5 radeon,ttm,drm_kms_helper i2c_algo_bit 13197 1 radeon $ lspci | grep VGA 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI M56P [Radeon Mobility X1600] $ xrandr Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 8192 x 8192 VGA-0 disconnected (normal left inverted right x axis y axis) LVDS connected 1680x1050+0+0 (normal left inverted right x axis y axis) 331mm x 207mm 1680x1050 60.1*+ 1400x1050 60.0 1280x1024 59.9 ....
