There are some cases where the VS is the only stage enabled, it uses the entire URB, and the URB is large enough that placing later stages after the VS exceeds the number of bits for "URB Starting Address". For example, on Icelake GT2, "varying-packing-simple mat2x4 array" from Piglit is getting a starting offset of 128 for the GS/HS/DS. But the field is only large enough to hold an offset of 127. i965 doesn't hit any genxml assertions because it's still using the old OUT_BATCH mechanism. 128 << GEN7_URB_STARTING_ADDRESS_SHIFT (57) == 0, with the extra bit falling off the end. So we place the disabled stage at the beginning of the URB (overlapping with push constants). This is likely okay since it's a zero size region (0 entries). It seems like the Vulkan driver might hit this assertion, however, and the situation seems harmless. To work around this, always place disabled stages at the start of the URB, so the last enabled stage can fill the remaining space without overflowing the field.

Support
-------
Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
To figure out who you're talking to, or which nick to ping for your
question, check out `Who's Who on IRC
<https://dri.freedesktop.org/wiki/WhosWho/>`_.
The next best option is to ask your question in an email to the
mailing lists: `mesa-dev\@lists.freedesktop.org
