@eggie You shouldn't be using nouveau on your hardware; it has almost no

FYI, this bug has nothing to do with the use of swap. It just happens

@mykizi-ericsson Could I get an update for my last comment? If CPU
hotplugging can't be addressed then perhaps it'd be alright to just mark
the new module parameter as unsafe...

Thanks for the clarification, that makes sense to me now. It doesn't
look like the patch handles CPU hotplugging though; a cpumask filled
with *only* offline CPUs can be passed as a parameter, or all of the
CPUs in the cpumask can be offlined after the setup is finished. This
isn't a problem with
It looks like the supplied patch is a no-op. A module parameter is
introduced with a .set function, but the parameter does not have any
write permission specified so the .set function can never execute (since
userspace won't have permission to write to the module parameter file).
