Comment # 9 on bug 1209436 from Matthias Pfafferodt

same problem here - switch back to 5.14.21-150400.24.46-default helped

if it helps, here the information about the graphics:

#> lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen
Core processor Graphics Controller (rev 09)

I have seen on the screen only messages about the TPM chip and then the system
hangs (something like 'error communicating to tpm chip'). If any debug
information are needed feel free to contact me.
