#This script will automate the reloading of the ivtv modules. It is rather heavy handed but due to
#issues with firmware failures in the ivtv module causing recording issues on my PVR-500 it was
#my last resort to prevent failed recordings. Note that this script must be run as root in order to
#be able to reload the ivtv module. As such it has full root privilege and should be used very
#carefully. While it works as intended on my debian system I cannot guarantee it will work as
#intended on your system. Please check all commands before using.

#Cron jobs start on the minute and so do myth recordings so wait 15 seconds
#for the problem to occur and be logged
/bin/sleep 15

#If we find an indication in the syslog that the ivtv driver has failed
if  /bin/grep "Encoder has died : ivtv_serialized_open" /var/log/dmesg.log ;  then

#Kill both frontend and backend so that we can unload the ivtv module

        #pkill mythfrontend
        #pkill mythbackend
        /sbin/sv restart mythbackend
        /sbin/sv restart frontend

#The ivtv module will not unload until the frontend and backend are stopped so
#rather than sleep for some arbitrary amount of time lets just try to unload

    #repeatedly until we succeed

        while ! /sbin/modprobe -vr ivtv ; do

        #Wait for a second

                /bin/sleep 1
                i=$(($i+1))

#See if we have tried more than 15 times indicating there is a real problem

                if [ $i -gt 15 ];then

         #In which case return an exit value of 1

                        exit 1
                fi
    #Otherwise try again
        done

    #Relax for a second

        /bin/sleep 1

#And reload the ivtv module the debug level is so that when someone tells

    #me what to look for my logs should have everything

        /sbin/modprobe -v ivtv debug=127

#We are moving the logfile to another file so that we can corelate the failures with
#Logs. the new file name is syslog.restart.n so check to see if n exists

        i=0
        while [ -e /var/log/dmesg.log.restart.$i ];do

        #and if so iterate until we find a good name
