Can someone try this on ppc64le system? At this point I am not convinced
this issue is generic.
Does your x86 system have at least 784 CPUs?

I don't know where the original report came from, but the trace shows
"CPU 784", which would usually indicate a system with at least that many
CPUs.
Update, apparently the report originally came from IBM, so I'll chase it
up internally.

I think you're right that there's probably no issue in the module code,
sorry to waste your time.

cheers
