https://bugs.freedesktop.org/show_bug.cgi?id=109206 --- Comment #53 from Ondrej Lang --- According to the linux kernel 5.2 changelog (https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.2), the fix for the DMCU firmware issue on raven1 platform is included in that release. I went ahead and tested this and can confirm that I was able to boot without a blank screen into my machine with kernel 5.2 without needing to use the workaround. I tested with: 1.) re-installed latest linux-firmware package 2.) installed kernel 5.2 3.) re-generated the initramfs 4.) booted into linux using kernel 5.2 and had no blank screen, dmesg output is clean with no erros for amdgpu Tested on: HP HP ENVY x360 Convertible 15-bq1xx/83C6, BIOS F.21 04/29/2019 I guess if someone else can confirm my findings, maybe on different raven1 hardware, this ticket can be closed. -- You are receiving this mail because: You are the assignee for the bug.
