** Description changed: + == SRU Justification == + + Impact: CONFIG_DRM_AMDGPU_CIK enables experimental support for some AMD + hardware in the amdgpu driver. It's not considered stable yet and is not + working properly with some hardware. + + Fix: Disable this option. The hardware which is no longer supported by + amdgpu is all supported by the radeon driver. + + Regression Potential: It's possible that some regressions might be seen + by users with affected hardware, but generally using radeon for this + hardware should be more stable. + + --- + Version 1.149 of the package does not have /lib/firmware/radeon/kaveri_sdma1.bin needed for the latest AMD DRM module. After booting my monitor is blank. For other AMD chipsets *_sdma1.bin is needed as well: drivers/gpu/drm/amd/amdgpu/cik_sdma.c(126): snprintf(fw_name, sizeof(fw_name), "radeon/%s_sdma1.bin", chip_name); Similar to https://bugs.launchpad.net/ubuntu/+source/linux- firmware/+bug/1183777, https://bugs.launchpad.net/ubuntu/+source/linux- firmware/+bug/1218691 Best regards, Timothy
