A real crash or just a locked-up system?
Comment 3 lars@bistromatic.de 2008-05-01 07:20:38 UTC 
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@bistromatic.de 2008-05-01 07:48:54 UTC 
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.
Comment 5 Bug Zapper 2008-05-14 10:26:16 UTC 
Changing version to '9' as part of upcoming Fedora 9 GA.
