Description john 2000-05-31 23:40:00 UTC

I have two Hauppage TV/PCI cards in my machine using the bt848 driver.
The fxtv application works great, even with two copies of it running
simultaneously (one on each card).

running 
sysctl hw.bt848 or
sysctl -a

will crash the machine (the -a version crashes during the hw stuff,
probably right at the bt848 part).  The crash is 100% reliable and 
always occurs, as far as I can tell.

Fix: 

Unknown to me at the moment.
How-To-Repeat: Install two Hauppage TV/PCI cards and run sysctl.

Does this problem still occur in newer versions of FreeBSD, 
such as 4.3-RELEASE?

I originally reported this problem, but I don't know if it still happens on
4.3.  I had to move by bt848 cards from my desktop FreeBSD box to another
machine running Linux because the Linux machine is part of a cluster that
we have.

Originator is unable to confirm whether this is still a problem in a 
newer version of FreeBSD, so I'm closing this PR.  If this is still 
a problem in a newer version of FreeBSD, a new PR should be opened.
