I have this strange issue that when I try to boot my old HP T520 Thinclient (AMD GX-212JC SOC, I think codename Kabini APU) into Fedora 44 using the default 7.1 kernel sometimes during the boot process the display (connected via VGA) stops getting a signal. The system boot itself seems to continue as I can SSH into the machine a bit later.
If I select the 7.0 kernel in the GRUB menu, it boots fine as before.
My initial suspicion was that it is related to the switch to the amdgpu driver by default in kernel 7.1, but after adding the kernel parameters to disallow the radeon driver and always use amdgpu, the issue remains. With Kernel 7.0 is runs fine using the amdgpu driver, but with 7.1 the display out breaks during boot before it reaches the login window.
Any other idea what might be causing this? Thanks!
Edit: Ah, it might be this bug.
