vv4.19.106-cip21-rt8 should be available at kernel.org.
We are only testing kernels in non-realtime configurations, but this
proved useful in this case, and uncovered problem on de0-nano (32-bit
arm). Bisecting was quite interesting, but in the end we got close

easy. Thanks for all the help (and that includes upstream). I still
need that or equivalent patch merged into -rt tree. Technical details
Trees are available at
And their content should be identical.
