Hyperthread support in QNX6.2.1

Hello,

I cannot get hyper-threading working in QNX 6.2.1. I get an error about CPU
1 failing to start.

I have tried using procnto-smp to no avail.

I remember reading a posting on the newsgroups, I think answered by Chris
McKillop, regarding this - but I cannot find it now.

Anyone got any experience?

Cheers,
Robert Muil.
