Verified patch from bug 1849278, created PPA https://launchpad.net/~vicamo/+archive/ubuntu/ppa-1849278 for it, and this does not fix the issue and the error messages can still be found. However, a v5.4-rc4 mainline kernel is immune from this issue, so we'll continue to find the fixing commit to backport.
