Discussion:
Hey @idscd, thanks for reporting. I can confirm this is still a problem (despite PR #16928), if the kernel takes too much time to start.

We'll try to fix this error in our next release.
OK, uninstalled 5.2.1, and went back to 5.1.5; all issues are gone now.
Right, but we still need to solve this error.
