I think I am suffering from a related bug. Asrock X370 Taichi, BIOS 5.10 (2018-12-21). Ryzen 5 2600X. Radeon RX 580. Ubuntu 18.04.02 (HWE). I tested with kernel 4.15 and 4.18, no difference.
Can not boot via GRUB with amdgpu driver, unless "amdgpu.dpm=0" is set. I only integrated the RX 580 into the build recently, after updating to BIOS 5.10 (AGESA 1.0.0.6), so I haven't yet tested previous BIOS versions with this card. I wonder if this latest BIOS update is affecting AMDGPU's DPM? https://www.asrock.com/mb/AMD/X370%20Taichi/#BIOS -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1809934 Title: AMD AGESA PinnaclePI-AM4_1.0.0.6 causes amdgpu hang on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1809934/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
