I installed Leap 15 on a Dell Precision 5820, which came installed with Ubuntu 16. I am using a legacy BIOS (not EFI) boot, even if the computer is EFI capable (and Ubuntu was in fact installed with an EFI bootloader). The disk also contains a 5Gb partition with some Dell diagnostics, which I thought better to keep. The system is fine, except that at boot it shows the error:

"Error parsing PCC subspaces from PCCT"

From some posts on Fedora it is suggested that this is a kernel bug: https://bugzilla.redhat.com/show_bug.cgi?id=1435837#c82

Other websites suggest that it might be related to the (possibly) mixed bios/efi boot.

Did anyone else experienced the same problem with Leaf 15?
