It seems there are a couple of msk(4) issues on Yukon Ultra and
Ultra II controllers. Some revisions appear to work without
problems but others didn't work well. You may have noticed there
are a couple of msk(4) related PRs. Perhaps I have to sit down and
verify every register access patterns and check controller status.
For long time, one of the problem was lack of hardware access.
There is no standalone PCIe Yukon Ultra/Ultra II controllers in
market so it looks hard to get it in near future. :-(
