Apologies if I'm causing too much noise.
While thinking about this I recalled that I changed amdgpu from modular to
static when I had problems with netconsole. I changed it back to
modular to see if that helps and I get the earlier mentioned hangs later
in the boot process when udevd starts and netconsole is up working.
This enables me to inspect boot messages and I tested with
amdgpu.discovery=0:
5,175,49060,-;Kernel command line: root=PARTLABEL=system1 amdgpu.discovery=0 loglevel=15 netconsole=...
I'm afraid I now get traces that commit b6df946ef4b5 (drm/amdgpu: fix
the nullptr issue as for PWR IP not existing in discovery table) is
fixing (output attached below) and I cannot decide how to continue with
bisecting...
