Re: 4.19.106-cip21-rt8 problems on de0-nano

Pavel Machek


I pushed candidate for -cip-rt, but it seems to fail on de0-nano
board. Code under testing is at:
It is pipeline

I'll reuse the branch for more testing.
I managed to narrow the bad commit to the -rt tree, between:

OK 122904930 pick 69aa73357e6a rcu: Don't allow to change rcu_normal_after_boot on RT

BAD 122882826 eae5a7cab722 sched/deadline: Ensure inactive_timer runs in hardirq context
And something went seriously wrong after these tests. I submitted same
tree twice, and got different results.

First this -- de0-nano succeeds:

Now this -- de0-nano fails (and ipc227e is unfinished for long time):

I'll need some help here.
