My system that is based on an ASRock X570 Pro 4 worked fine for several years. Now it no longer boots without a workaround.

I get a number of errors and then a black screen. The errors are:

[1.1645141 ACPI BIOS Error (bug): Could not resolve symbol [\SB.PCI0.GPP0.VGA.LCD._BCM.AFN7], AE_NOT_FOUND (20210730/psargs-330)

[1.1657311 ACPI Error: Aborting method \SB.PCI0.GPP0.VGA.LCD._BCM due to previous error (AE_NOT_FOUND)))

Then there are two more that complain about symbol [\SB.PCI0.GP17.VGA.LCD._BCM.AFN7].

I have Linux Mint 21 installed, and the latest BIOS 4.30. Sometimes, the boot process gets to Grub, then followed by a black screen, sometimes just the black screen.

The workaround that permits booting in most but not all cases is to enter the BIOS, make some seemingly arbitrary change to settings, save settings, reboot. Then boot is usually successful.

The same set of symptoms occurs when I try to boot from a freshly downloaded Linux Mint 21 USB stick. This makes me think that there is something wrong with the board itself, not with my OS installation.

Thanks for helping!

I know you use Linux, but did you try, for sa test, to conenct an SSD or such, and install Windows 10.
You can use it without registering for 30 days.
Install with default BIOS settings, if this works without problems, it is an OS problem, and the open source forums can maybe help
Kind Regards

Try different distros.
I use Ventoy on one USB flash drive, you can put any ISOs you like that will fit and boot any of them.
