I installed the 5.13.1-300 kernel. Booting this kernel, the display (after the GRUB menu) becomes black. Serial connection works. I booted again the 5.13 kernel, but no way, the display is black. So I selected the previous 5.12.14-300 kernel, and the display continues to be black. Mh? Uninstalling the 5.13.1 kernel and booting again with the 5.12.14 one, then the display starts to work again. Do you have any idea why if the 5.13 rpm is installed the display doesn't work even booting a previous kernel? (Or I'm missing something?) Ciao, A.
