AMDGPU Driver not loading on kernels newer than 5.6.6

Ask Fedora

I tend to reboot very infrequently. Last evening I did, and it did not go well. All my kernels (5.6.8, 5.6.10, 5.6.12) all fail to load the amdgpufb driver and gets stuck at a black screen. Thankfully 5.6.6 works fine. Any tips on what to look into here?

I did look at what packages were there for each kernel release and I have all them:

[andrew@schotty-tower-wired Desktop]$ rpm -qa | grep kernel | grep 5.6.6
kernel-core-5.6.6-300.fc32.x86_64
kernel-modules-5.6.6-300.fc32.x86_64
kernel-5.6.6-300.fc32.x86_64
kernel-devel-5.6.6-300.fc32.x86_64
kernel-modules-extra-5.6.6-300.fc32.x86_64
[andrew@schotty-tower-wired Desktop]$ rpm -qa | grep kernel | grep 5.6.12
kernel-modules-5.6.12-300.fc32.x86_64
kernel-core-5.6.12-300.fc32.x86_64
kernel-modules-extra-5.6.12-300.fc32.x86_64
kernel-5.6.12-300.fc32.x86_64
kernel-devel-5.6.12-300.fc32.x86_64
[andrew@schotty-tower-wired Desktop]$

And to answer the obvious – I did ssh in from another machine and update things quickly hoping that it would resolve things, but nope.

In case it matters, I have an rx590 installed in the system as my only GPU. My i7-4790k does not do graphics on chip, requires a discrete card.

Thanks much!
Andrew.

This is most obviously a bug. You will want to open a report at bugzilla.redhat.com against Fedora 32 and the AMDGPU module and explain the situation there.
