Description Simun Mikecin 2003-10-05 11:30:21 UTC 
	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.

Fix: 

None that I know of.
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

I'm aware of this problem.  The driver currently lacks all of the important 
locking woodoo for smp-safeness.  It's on my TODO-list, so I'll take care 
of this.

alex has given up his commit bit.  Reset Responsible to roger, since 
he is listed as the bktr maintainer.

Assignee is currently away from doing FreeBSD work at the moment, so 
at his request, return this one to the pool.

If this is still an issue with a supported FreeBSD please reopen this.
