Might try unplugging a few minutes.
Also might try resetting CMOS, usually
a jumper on the board.

I had an A7V-E where the onboard Rhino
ethernet would fill up dmesg with error
messages.  Also ethernet transfers would
gradually grind to a halt.  Unplugging it
a few minutes cured it.  Been running fine
many months since.
