>Description:
Computer freezes if using SMP on HT-enabled uniprocessor with
enabled 2 logical cpus. If I disable logical processors (but still
use SMP kernel) it works OK. I haven't tested it on a real
multiprocessor machine.
>How-To-Repeat:
you can reproduce a system freeze like this:
1. start fxtv (port multimedia/fxtv)
2. close fxtv
3. start fxtv for the second time
>Fix:
None that I know of.
