I clearly explained why this has crossed a line in the prior mail. Cutting that
part off won't make it go away.

Stop the handwaving and stop claiming things that aren't true. The links in the
prior mail clearly disprove any of your claims. I did not acknowledge any bug.
And I did not do so because you have not provided any proof that this leads to
any issues. You claim that there are bugs. So the burden of proof is on you to
spell them out clearly and provide reproducers where this actually leads to
issues.

If that really was your intention then again, you could have easily handed in a
session to either one of the microconferences that I ran and presented in, you
could've easily asked for a hackroom session. You could've written a normal
mail addressing the issue. None of that happened. Your actions clearly speak
against any intention of resolving this constructively so far.

It is not our task to to chase after you in order to get you to tell us
what your problem is. You need to find better, less passive-aggressive
ways to deal with your frustrations.

Here is my proposal to resolve this. The Linux Plumbers infrastructure is well
alive and running and always there for on-demand meetings. I offer you a
virtual meeting with camera and audio to clear the air both socially and
technically. We will ask someone to be around as arbiter and to take notes
during that meeting so we have a track-record.
