Hello, I have an AMD Ryzen with a Vega 56 graphics card running Fedora
30 and the 5.0.17 update the graphics output seems to just die after
grub. Rolled back to the previous kernel (5.0.16) in grub and it comes
up just fine. No errors or logs ... just sits there at the ASRock logo
on screen after selecting the kernel. From what I can tell it is
actually installed. Tried runlevel 1 and 3 as well and it does the same
thing. The kernel works fine on my laptop but that's an Intel machine.
Standard grub command line arguments except amddgpu.gpu_recovery=1 for
the Vega card. I did also try it with that removed and still no go. I
can SSH into it just fine but the screen is just sitting there with the
BIOS manufacturer's logo, nothing telling in dmesg or /var/log/messages
and it doesn't set off abrt.
I'm running a pretty standard Fedora system with only some codecs and
non-free software from rpmfusion. The only other thing I changed
recently was adding the ROCm for OpenCL image support on my Radeon card.
I removed those after I noticed this issue and reran dracut to no avail,
reinstalled the kernel and all related packages as well. Nothing.
Anyway, looks like I really loused something up. Luckily the older
kernel still works fine. Any other ideas out there? Maybe the ROCm
packages left something behind (removed with dnf remove)?
