A real crash or just a locked-up system?
Comment 3 Lars Hamann 2008-05-01 03:20:38 EDT
No, a real crash. I.e.:
No response to mouse or keyboard.
Can't connect/ping from another machine. 
No log entries in /var/log/messages.
Only way to revive it is the reset button.
Comment 4 Lars Hamann 2008-05-01 03:48:54 EDT
I've done a few more tests. 

The Bt878 card is all it needs to trigger this bug. 
The SAA7146 alone works OK. The Bt878 alone crashes the machine.

Changing version to '9' as part of upcoming Fedora 9 GA.
