Yes I'm seeing a lot of bounces from the linux.intel.com mailserver lately
(and only from that mail server and not from any other mailservers).

You should have also received a copy through the intel-gfx lists though.

Or you can grab a raw copy from patchwork.

Regardless of the mail-issue a review would be much appreciated.

Regards,

Hans


p.s.

While on the subjects of bouncing emails, did you see Jani's reply to:
https://patchwork.freedesktop.org/patch/422669/

Where he asks for a second opinion on that patch from you ?
