Re: realtime on de0-nano bisection

Hi!

I'm fighting with realtime on de0-nano, and I could use some
help... locating the bad commit. I don't seem to know enough about
test infrastructure to be effective. I pushed a tree I'm interested in
to:

https://gitlab.com/cip-project/cip-kernel/linux-cip/tree/ci/pavel/linux-cip

And I believe regression is somewhere in there. I just don't know
where.
What Kernel config are you using?


List of commits is below. I believe 4.19.106-cip21 is okay while
4.19.106-cip21 is bad, and I have done some tests, but now it looks
Do you mean 4.19.106-rt44 Is bad?

like tests are unreliable (and even my basic assumptions may be worth
re-testing).

Can you help? I'll be away from console for a few hours now.
I'll get bisecting.

Regards, Chris


Thanks and best regards,
