Hi,
Would you have a serial cable to check early boot messages?
Yep, once it starts booting, this is what I get -
Booting `openSUSE Leap 15.2'
Loading Linux 5.3.18-lp152.47-lpae ...
Loading initial ramdisk ...
EFI stub: Booting Linux Kernel...
EFI stub: Using DTB from configuration table
EFI stub: Exiting boot services and installing virtual address map...
EHCI failed to shut down host controller.
I can probably get the output before that by running a capture, if it is
interesting.
In my experience the things after that are more interesting ;-)
In grub, edit the command line, put "console=ttyS0..." last (after
"console=tty") and maybe add "earlyprintk=serial,ttyS0,115200", then
remove the "loglevel=...", "splash=..." and instead add "debug" to get
as much output from the kernel as early as possible.
Good luck :-)
