Red Hat Bugzilla – Bug 220916
can't restart X after watching TV with SAA7134 TV tuner card
Last modified: 2007-12-11 03:09:55 EST
Description of problem:
I installed a KWorld Global TV Terminator card, which is SAA7134. It works
fine using tvtime, but it's impossible to restart X afterwards (though X
continues to work fine up to when the restart is attempted).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install a SAA7134 TV tuner card.
2. Put the line "options saa7134 card=65 tuner=54" to allow detection (it isn't
3. Watch TV using tvtime.
4. Log out, which causes an X restart attempt.
X won't restart. A text-based X configuration tool offers to let me try to
reconfigure X. This fails to get X working again. However, upon a reboot, X
works normally again.
X should work normally.
Using Intel 82865G integrated video. I checked that the trigger for the
problem is using tvtime to watch TV. If I don't watch TV, then X works normally
on logout. I'm assuming this is a kernel bug since only a reboot fixes it (AFAICT).

Actually it's only necessary to put "options saa7134 card=65" in
modprobe.conf, specifying the tuner isn't necessary. It doesn't affect the bug
Still exists in kernel-2.6.19-1.2895.fc6.
Still exists in FC7 kernel-2.6.21-1.3194.fc7.
Still exists in kernel-220.127.116.11-27.fc7. BTW, the problem does NOT happen when
using Fedora's new xawtv instead of tvtime to view TV. Go figure.
Does not happen any more with F8 and the latest kernel. Closing since I'm no
longer using F7 and can't check it there.
