Problems with NetBSD 9 on Pine RockPro64 board.

Hi !

After 9 hours of running ( during that system was downloading src tree
netbsd-9 from CVS), system lost tcp connectivity. Ethernet adapter
diode is flashing slowly, hub marks connection as inactive. Login on
serial console gave only message "Last login ..." and freeze. Enter
moves to the new line only, no other reaction. 
i'm connected to the console using minicom. 

Board Pine RockPro 64 with 4 GB memory, system on SD card (64 GB). No
other devices connected.
