Well, there aren't many real bugs. There are known omissions and regressions
(things that did work, do no longer work after releasing a new kernel).

IMHO, this doesn't help if we don't have people with enough expertise
to fix them. If issues are not quickly fixed, all those do not report a
second time.

And to be honest: there may be a lot of false alarms to filter out.
Therefore I prefer a beta-test (i.e. small group of testers) to having
all the world as testers.

Yes, good ideas. But it is not my focus to do that. I am not at all
working on firmware images, so I can only hope that someone is
picking this up.

Yes, this is not required. Unless it does not boot. But then
the issue can usually be found by people with a serial cable.
