[mythtv-users] Card settings seem to get corrupted/disappear on reboot

[Justin Walther]

Hey folks,
I've been experiencing this problem on and off now since upgrading to
.17.  For other reasons, I reboot my mythbox every morning at 5am. 
For the past week or so (no other changes made), upon reboot, I get
these messages in my backend log:

2005-04-16 05:01:43.049 Channel(/dev/video0)::Open(): Can't open video
device, error "No such file or directory"
2005-04-16 05:01:43.066 Channel(/dev/video0)::Open(): Can't open video
device, error "No such file or directory"

I have 2 pvr-250s.  The temporary fix I have found is to run
mythtvsetup and have it remove my card settings and then reconfigure
both cards.  Just this morning I noticed that my /dev/video devices
have a timestamp after 5:01am, the time of the errors above:

[root at mythbox ~]# ls -l /dev/video*
lrwxrwxrwx  1 root   root      6 Apr 16 05:02 /dev/video -> video0
crw-------  1 mythtv root 81,  0 Apr 16 05:02 /dev/video0
crw-------  1 mythtv root 81,  1 Apr 16 05:02 /dev/video1

Is it possible that the devices aren't being defined before the
backend is trying to access them?  If so, I'm not sure what has
changed to cause this.  Any advice would be appreciated.

Thanks,
Justin
