Kernel 5.10.36 and StrongARM SA1110 (Jornada 720)

Wed May 12 11:09:32 PDT 2021

Hello!

I want to know if anybody out there got the Kernel Version 5.10.36 to 
boot on this platform? For me it is stuck at "Run /sbin/init as init 
process" so it seems that it doesnt load init - not with Debian Lenny 
and not with BX emulation and Debian Stretch (tried sysvinit and 
systemd). It is alway stuck at "Run /sbin/init as init process". Older 
4.x or 3.x Kernel work like a charm - even with BX emulation and Debian 
Stretch. Would be great if anybody out there can help me

Regards

Stefan Lehner
