The Bugzilla at https://bugs.freedesktop.org is our tool of choice for
tracking bugs in drm/i915. It's your choice to not create an account
there, but please, don't expect us to work as a proxy between you and
bugzilla either. It's a much bigger and unscalable inconvenience for us
than it is for you to create that account.

I won't claim your bug will be fixed any faster if you choose to create
an account, but it's much more likely it won't get lost and forgotten in
the never ending stream of emails we all get.

Yes, please.

I'd also like to get a full dmesg from you, with drm.debug=14 module
parameter set, all the way from boot to the problem.

However, personally I find it a bit obnoxious to send big logs by mail
to hundreds or thousands of other people on the lists who really aren't
at all interested in them. Maybe you don't mind bothering them? It's
also not good to hide it away in my private inbox alone, because there
are other developers who will be interested. It has also proven to be
problematic to upload files to pastebins etc. where they expire at some
point in time, usually when we'd like to have a look.

Again, the obvious solution to the above is to file that bug and attach
the dmesg there, at the unfortunate slight inconvenience of you creating
an account there.

Your call.

BR,
Jani.
