I just installed 5.8 from buster-backports along with tesla-440 driver 
and it seems to give slightly better results,the modules build and load, 
but similar errors in kernel:

I don't mind waiting for a newer release, or using an older kernel, 
however any suggestions to solve the problem would be appreciated, even 
outside this particular bug report.
