I'm seeing a boot regression on a Power9 pseries LPAR. The system
hangs very early during boot after:

Quiescing Open Firmware ...
Booting Linux via __start() ...
That is strange. not sure where to look at without any logs.
Is it a specific config that fails or this specific LPAR that fails?
Is this a specific lpar or all power9 pseries are exhibiting same
behaviour?
Its specific to a lpar.
I am working on this, [...]
Great, thx.
Can you also confirm the same.
Na, sorry, can't help, I'm not affected, I'm just keeping an eye on
regression to ensure they are fixed.

Ciao, Thorsten
