----

Since kernel 5.5.x this error exhibits:

BAR 0: error updating

It appears to be a regression from 5.4 where the error does not exhibits -
enclosed accumulated kernel logs. 

It may or may not cause issues for the atheros drivers as mentioned in bug
209751.

I have tried to narrow it further down to a particular commit from the 5.5
branch but unfortunately the kernel does not compile then.
