https://bugzilla.kernel.org/show_bug.cgi?id=199567 Bug ID: 199567 Summary: [amdgpu] just a black screen irrespective of amdgpu.dc=1 or 0 at boot on kernels 4.17-rc2 and onwards Product: Drivers Version: 2.5 Kernel Version: 4.17-rc2 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: untaintableangel@xxxxxxxxxxxxx Regression: No Hardware: AMD RX480 (XFX black edition Currently using amdgpu and testing how awesome dc code is coming along on a custom kernel. Shortly after the patches went through the other week that stopped the recent flickering, everything was (and still is) fine on kernel 4.17-rc1. Patches prior to rc2 (and onwards, including latest build and rc3 when tagged which are still broken for me) cause an unresponsive black screen on loading the kernel. Have to manually restart into another kernel. As far as I can tell, there were 3 patches to this area before rc2 was tagged https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=221bda4b5f1abfd74159d7bf3703affa62468030 but I tried reverting the one intended to fix 'black screens' without success. However, just after rc1 was tagged, there's a big chunk of patches https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8089f9f5a32938ddefb1767b8ee14bb7996e5e2f so it might have been something in that? If so, the problem still exists in what will become rc3 at the time of writing. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
