In #1446 the original reporter has offered to bisect, I didn't see
further feedback yet.
I'd be willing to contribute a small amount of time on the RX 6800 XT if
I am able to get the card and if I feel the time will be productive, for
example, if somebody more familiar with it can give me some specific
things to test.
I would genuinely like to have the benefits of PCIe 4 and 16GB video RAM
too but the cards are simply not available here.
As the Navi 2 cards appear to be more suited to my purposes, I wasn't
really interested in spending time or money on the Navi 1 cards. I'd
rather just put the effort in with a Navi 2 card.
I have some good news, there is a fix for my issue, actually in 2
parts, both in the generic amdgpu memory management code. IMO it's
worth to retry on the other cards as well.
