Another information:
I'm trying nouveau with nvidia PRIME and there are no lockups with this setup.

The issue I've here is now that the powerconsumption is with dicrete card render offload very high around 15W compared to switch off the card via acpi 7W.

cat /sys/kernel/debug/vgaswitcheroo/switch 0:DIS: :DynOff:0000:01:00.0
1:IGD:+:Pwr:0000:00:02.0

 xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x8d cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 4 associated providers: 1 name:Intel
Provider 1: id: 0x65 cap: 0x7, Source Output, Sink Output, Source Offload crtcs: 4 outputs: 2 associated providers: 1 name:nouveau

I can switch off the card completely via acpi_call but then the lockups are popping up again...
