Board lost? (OrangePi One)

Hallo, I use Armbian for some time now, usually I can solve all problems myself. Recently, one of my boards has gone bad (or mad?). I started using this particular board on 10/11/2016. Installed Armbian (5.20) from images available on that day. Everything went nice, no problems, pretty much no load for whole days. On 20/12/2016 something began to use 1 core of CPU. No idea what. On 23/12/2016 board stopped responding completely. I haven't accessed/used system from 20/12/2016 so I was not aware of problem. I turned it off later.

I removed SD card from board and used with other OrangePi One just fine. But this board behaves strange. I re-installed Armbian and it seems to work. Sort-of. cfinteractive plus watchdog consume 100 percent of CPU (I mean 1 core).

dmesg - after boot first 4 messages are "wait hard syn message time out" followed by plenty of "hw message queue fifo full timeout" Only thing I manage to google is source code related to these messages.

I'll gladly provide additional information.

Only strange ting hardware-wise I noticed: black plastic on pin headers seems to pull pins together and thus bend board slightly, but noticeably. So I removed plastic with pliers just to relieve board from unnecessary stress. I did that with all of my Oranges (Ones, PCs). Boards are definitely straighter.

Is this OPI One FUBAR? How could that happen?
