Hi,

thank you for keeping eyes on progress here, and sorry for not resolving
this so far.

I plan (and my manager agrees :)) to work on this ~now

So far I have found a few bad smells to fix in related area, will work
with Ubuntu as main test setup for that too to increase a chance of
repro.

Also, just from the code there is no obvious bug (even if there is about
one patch around stats in 6.1 ... 6.2 range).

I would also check exact Ubuntu kernel sources (not just "upstream").
