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.

--- Comment #1 from Alex Deucher alexdeucher@gmail.com --- Can you bisect? If you set modprobe.blacklist=amdgpu on the kernel command line in grub and you are still getting a problem, it's an issue outside of the graphics driver. If so, does setting pci=noacpi help?

--- Comment #3 from Samantha McVey samantham@posteo.net --- I was able to get something on the screen when I added "pci=noacpi" (this was without blacklisting amdgpu).

I uploaded an attachment which shows the full output (I only typed out the first several lines).
I might be able to bisect if needed. Does the image I uploaded show you anything useful?

--- Comment #4 from Samantha McVey samantham@posteo.net --- I just tested on the latest git (v4.19-rc7-15-g64c5e530ac2c) and I didn't see any issues. So the issue has been either fixed between 4.19-rc7 and latest git or something in the kernel config is different.

--- Comment #6 from Samantha McVey samantham@posteo.net --- It turns out it is config related, as I compiled the kernel with my old config instead of a minimal one, and I had the same boot issue. I posted about my issue here https://bugzilla.kernel.org/show_bug.cgi?id=200087 since that may be the same bug.
