5.4 not running HTT
I have several boxes that I have upgraded from 5.3 to 5.4 and has stopped using the HTT virtal CPU's. This have been going on for a while. the oldest is dated 20050519 and the latest is yesterday. Is there something that I have missed? Been using same configs for 5.3 without any problems. /Bjorn Little outputs from yesterdays build: # ps aux | grep idle root 12 99.0 0.0 0 8 ??

Quite right -- we fell into the trap of just following our standard procedures, instead of thinking about whether this met the test for being documented in UPDATING (which it certainly does, since it is a potentially astonishing user-visible change). I've added it to the stable branches, but not to -current, since hyper-threading is still enabled by default in HEAD.
