Bug ID: 108307 Summary: Regression: Raven Ridge 2700U does not boot with 4.19-rc7 Product: DRI Version: XOrg git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: samantham@posteo.net
I have a Lenovo A485. Kernel 4.18.12 works fine for me, but I have tried almost all the RC's (1, 5, 6, 7) and the screen turns black when GRUB would normally be showing "loading initramfs" or it freezes when it's showing "loading initramfs".
lspci -nn 05:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Raven Ridge [Radeon Vega Series / Radeon Vega Mobile Series] [1002:15dd] (rev d0)
I found this bug report which seemed similar to what I was experiencing, but my firmware is up to date https://bugs.freedesktop.org/show_bug.cgi?id=107880 [ 2.814558] [drm] Found VCN firmware Version: 1.73 Family ID: 18
I tried: modprobe.blacklist=amdgpu and that did not change anything.
Let me know how I can help troubleshoot this problem. Thanks.
