Comment 19 for bug 2037604

Ok, I've tested on Intel gen9 (KBL) and gen12 (ADL) so that side is covered too. Gen11 (Ice Lake) is rather rare, so these two generations cover enough.

The issue I had with DG2 on 6.1 OEM kernel was caused by missing a commit which allows reducing the minimum memory alignment. I've reverted the commit from mesa, as that way things work the same as before, and is safest regarding updates. This issue is tracked on bug 2051068. Once the new upload is in proposed, *this* bug can be marked as verified.
