adapter lockup

I'm using TechnoTrend 1500/1600 cards (Premium-S) and they like to lockup randomly. For example I'm seeing situation when one of two configured adapters hangs and I get output only from one adapter. dvr.c has a hack for Flexcop cards and on debug output I have seen that bouncing filter works for TT card reanimation but every now and then it does not. I would like to detect such situation, getstream could die and I would do some scripting for bringing everything up again (module reload or even reboot). Should it be implemented in internal watchdog or in dvr_stuck_timer, maybe some retry-counter with SIGABR when reanimation does not work for a card after N tries? -- .: Jakub Paweł Głazik, .: email & jabber: zytek<at>nuxi.pl
