Na 4.7 eu reportei para o suporte da mikrotik esse problema de travamento
depois da inicializacao depois de reboot, mais eles me responderam 
para acessar a rb com cabo seria, rsrsrsrs
Eu doido para ganhar uma licenca grátis, porque quem relata um problema 
para eles, e depois sai uma correcao ganha uma licenca parece, mais...
Fica para a proxima, hhauaha

What's new in 4.9:

*) fixed problem - some of the bridge ports stayed invalid after reboot;
*) console - added '/port remote-access export' command;


What's new in 4.8:

*) fixed problem - WinBox crashed while opening VAP interface;
*) dhcp server - fixed possible inactive dhcp server in case of many
   dhcp leases with address-pool enabled (broken in v4.7);
*) dhcp server - show non-printable agent-circuit-id and agent-remote-id
   values in hexadecimal notation (the same way as client-id is shown);
*) api - can supply password to '/system/upgrade/upgrade-package-source/add';
*) console - fixed bug that caused "cannot set ..." error when using
    some properties in 'find' commands;
*) api - 'print' command was not showing values of some properties
    such as 'servers' in "/ip/dns";
*) show old software id in export file header;
*) added support for secondary serial port on RB800/RB1100;

Será que desta vez testaram por lá ? 
Foi uma furada das grandes, nao passou nem 2 dias no Servidor e 
removeram a 4.7
