2.9.20 "System rebooted because of kernel failure"
I have recieved confirmation from MT that they are working on this problem. We have this .20 version rolled out to maybe 10 routers in production and have seen the kernel error on 4 of them so far. The routers reboot or the routers lock up. There needs to be better communication on serious errors like this. If a serious problem like this is found in a version, everyone should be notified so we do not continue installing it.
We loaded 100 brand new Mikrotik Routerboards with 2.9.20 and now have to go through the trouble of downgrading or upgrading.
