We tried to analyse but it is unilekely. It may just be wear somewhere else. I also see XUDF error reports from I2C from time to time and it seems to depend a little on battery charge.

Be warned, I have no experience with mainlining patches, even not with kernel programming at all. Therefore I need someone holding my hand. Does anybody volunteer? Yes, we all :) Basically the task is to a) shape (i.e. rebase, edit) the patches according the rules: https://www.kernel.org/doc/html/latest/process/submitting-patches.html b) add Signed-Offs etc. c) compile test d) git format-patch e) ./scripts/checkpatch.pl and fix any reported weaknesses f) send by mail to this audience (perhaps check with ./MAINTAINERS) > > I had a look to the branch Nikolaus pointed out.

Yes. > - Where should I send the patches? The current audience might be a little bit large? The audience is usually defined by ./MAINTAINERS And whoever could contribute in review.
