Hi,

I updated my arm64 tree from beginning of Feb to today and I am gettig as
far as "Loading splash ok" (I am netbooting):

OK boot -v
Loading kernel...
/boot/kernel/kernel text=0x318 text=0x9a04f8 text=0x2cba18 data=0x180af0 data=0x0+0x371000 0x8+0x170778+0x8+0x1a1e2c-
Loading configured modules...
can't find '/etc/hostid'
can't find '/boot/entropy'
Using DTB provided by EFI at 0x3e6c2000.
Loading splash ok


After the reboot I checked in loader how console got set:
console=efi,comconsole

This time it still stayed blank but rebooted by itself after a few
seconds.

OK set console=comconsole
OK boot -v
Using DTB provided by EFI at 0x3e6c3000.
Loading splash ok

and that also just rebooted itself again.


Then I went to laoder_4th,efi to check that:

and I got the nice blue "Booting..."

OK boot -v
Booting...
Using DTB provided by EFI at 0x3e6a3000.
Loading splash ok

But nothing else either.


Another few tries later I managed to catch this:

OK boot
Using DTB provided by EFI at 0x3e6c2000.
Loading splash ok
