I don't expect much from a 10$ board so I will not complain but I would like it to reboot when there is a kernel crash. I have put: kernel.panic=3 It was on 10 seconds by default and it still didn't reboot. Any ideas? Link to comment Share on other sites More sharing options...

Would solving the problem (preventing the 'kernel crash') also be an option? How do you power the board? Micro USB? Link to comment Share on other sites More sharing options...
postifix Posted March 7, 2018 Author Share Posted March 7, 2018 No through the GPIO, I have a dedicated 2A psu so that is not a problem. I doing massive disk IO operation to a disk attached to it via USB that crashes it. If I don't run anything there are no kernel messages or crash and it stays up for weeks.

Well, amperage ratings are pretty much useless if the problem is a voltage drop under load (which is a very common problem BTW). I would try to measure voltage on the board's testpoints to check for this. And also try to rule out the other hardware issues, eg. bad DRAM: https://forum.armbian.com/topic/6667-solved-upgrade-process-is-broken-on-opz2-h5/?do=findComment&comment=50651 Link to comment Share on other sites More sharing options...
