Has anyone else noticed that whilst GRUB boot parameters seem to resolve
the problem (perhaps with some decrease in performance) the system will
once again freeze upon resuming from a suspend (closing laptop lid)?

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...
