Created attachment 130563 [details] dmesg The machine completely freeze using radeonsi driver with FirePro W600, W9000 and W9100. * Steps to reproduce: wget http://www.phoronix-test-suite.com/benchmark-files/GpuTest_Linux_x64_0.7.0.zip DISPLAY=:0 ./GpuTest /test=fur /fullscreen * Acutal result: System and screen are frozen after a few minutes (sometimes a few seconds, sometimes 20 min). No mouse/keyboard. Does not respond to ping. No kernel panic. Requires hard reboot. After reboot, no error in /var/log/kern.log. Empty dir /var/crash, empty dir /sys/fs/pstore. Sometimes some nul characters ^@ just before the next "Linux version". Using a serial console does not show additional debug messages. * Expected result: No system freeze. * List of things that have been tried but leading to the same result: - kernel 4.4.X, 4.8.x packaged by ubuntu. - amd-staging-4.9 from https://cgit.freedesktop.org/~agd5f/linux. - a few 4.10 kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/ . - radeon.dpm=1 (all values for power_dpm_state / power_dpm_force_performance_level) - radeon.dpm=0 (power_mode=profile and all values for power_profile) - radeon.msi=1 / 0. - DRI2 / DRI3 - glamor / no accel, TearFree on / off - single monitor, multi monitor, resolutions 1600x1200, 1920x1080. - Latest libdrm / mesa. llvm 3.8, 4 and 5. * List of things that avoids the system freeze: - radeon.gartsize=512 radeon.vramlimit=1024 * Others: - apitrace trace then replay does not lead to the freeze. - No errors with R600_DEBUG=* or MESA_DEBUG. - strace sometimes shows that the last call is ioctl(RADEON_CS) but not sure how reliable this is provinding the last print might not be flush. - Happens with 2 differents brand for the mother board. - takes a bit longer for the mentioned GpuTest to freeze the machine on W9000 and W9100. * TODOs: - Try again kgdb. - Try amdgpu instead of radeonsi.
