Created attachment 123454 [details] /var/log/syslog at the moment of hangup (photo) System: Ubuntu 16.06 with Mesa git (padoka ppa) and kernel 4.6-rc6 GPU: Intel HD 5500 + AMD R5 M330 - all command below run with DRI_PRIME=1 I get GPU hangups, which result in freeze after a soft reset, whenever the load is high enough to push the GPU into higher power states. If I run, for example, glmark2, only the first frame gets rendered and then the GPU lockups. After ~30s system freezes with information about GPU soft reset as the last message in syslog (see attachment) If I run a non-GPU-intensive commands (say, glxgears with vsync), then the GPU stays in low power states and I do not get this hangup. If I force lower power states (echo battery > /sys/class/drm/card1/device/power_dpm_state), I don't get this hangup even with glmark2. If I force high power states (echo performance > /sys/class/drm/card1/device/power_dpm_state; echo high > /sys/class/drm/card1/device/power_dpm_force_performance_level; echo on > /sys/class/drm/card1/device/power/control) then I do not get the hangup as long as there is no activity at all on the GPU. A simple glxgears is enough to trigger a hangup in this situation. This bug is present since at least kernel 4.2. I would appreciate any info on how to debug this further and will provide more info if requested.

Please attach your xorg log and dmesg output.

I've checked with Mesa 10.4.7 and kernel 3.17 (the earliest versions I could compile or run, respectively) and get the same lockup.
Can confirm this bug with a R5 M240 on a Thinkpad T450.
Does it work any better with my drm-next-4.8-wip branch: https://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-4.8-wip and the new smu firmware here: http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/commit/?id=9693ff6d749dcf1dfd81f0f6b227ab07a3d76c90

I've put new firmware files in /lib/firmware/radeon and I believe it is being loaded (the filesize reported is that of hainan_k_smc.bin): Jun 10 16:02:49 Sulejman kernel: [ 511.257607] [drm:radeon_ucode_print_smc_hdr] SMC Jun 10 16:02:49 Sulejman kernel: [ 511.257608] [drm:radeon_ucode_print_common_hdr] size_bytes: 61932 Jun 10 16:02:49 Sulejman kernel: [ 511.257609] [drm:radeon_ucode_print_common_hdr] header_size_bytes: 36 Jun 10 16:02:49 Sulejman kernel: [ 511.257610] [drm:radeon_ucode_print_common_hdr] header_version_major: 1 Jun 10 16:02:49 Sulejman kernel: [ 511.257610] [drm:radeon_ucode_print_common_hdr] header_version_minor: 0 Jun 10 16:02:49 Sulejman kernel: [ 511.257611] [drm:radeon_ucode_print_common_hdr] ip_version_major: 6 Jun 10 16:02:49 Sulejman kernel: [ 511.257612] [drm:radeon_ucode_print_common_hdr] ip_version_minor: 0 Jun 10 16:02:49 Sulejman kernel: [ 511.257613] [drm:radeon_ucode_print_common_hdr] ucode_version: 0x01337baa Jun 10 16:02:49 Sulejman kernel: [ 511.257614] [drm:radeon_ucode_print_common_hdr] ucode_size_bytes: 61676 Jun 10 16:02:49 Sulejman kernel: [ 511.257614] [drm:radeon_ucode_print_common_hdr] ucode_array_offset_bytes: 256 Jun 10 16:02:49 Sulejman kernel: [ 511.257615] [drm:radeon_ucode_print_common_hdr] crc32: 0x9624ad7c Jun 10 16:02:49 Sulejman kernel: [ 511.257616] [drm:radeon_ucode_print_smc_hdr] ucode_start_addr: 65536
I also tried the drm-next branch and the new firmwares, didn't help me either.
