I am assuming you mean that disabling hyperthreading logical CPUs help
on these issues ? Well, it does not make much difference here.
Suspend/resume works, but console switch is broken, triggering these
rather scary scheduling errors (and it's still broken when taking
ht-CPUs offline first). And console switch issues can probably affect
suspend/resume in bad ways.

Also tried enabling message signalled interrupt for the nvidia device,
but that does not change anything, so went back to default. I'll be
heading back to 195.X and officially give up until some new nvidia
driver release appears, since the problem is the same across several
kernel releases, up to the very latest.
