m4v2 Get wrong frequency,

I've got an m4v2 running current armbian (Armbian_19.11.4_Nanopim4_bionic_legacy_4.4.192_desktop.7z)

 

I get a stack of messages on tty1 and in dmesg stating "get wrong frequency".  it was also logging via syslog, but I have disabled those from logging.  it also seems to generate one of these messages every time I hit a key on the keyboard.  somehow related to kbd interrupt?

 

ondemand cpu freq scaling works,  running cpu intensive jobs, the following frequencies were observed

i see.  that is a pity, as it makes text console almost useless, as well as dmesg output.

 

as a side note, if I run latest Friendly desktop, I don't get these.  I'll have a bit more of a dig about 

 

is there an easy way to recompile one of these dts files so I can test with "delete node" removed?  or I may checkout trying the one shipped with friendly desktop as a test
