  (No new failures associated)
Comment 2 Chris Wilson 2019-10-22 12:07:21 UTC 
I was expecting to see it filed as "failed to timeslice into queue". Both are just a timing issue. The former I expected to have been nailed.
Comment 3 Francesco Balestrieri 2019-11-01 05:58:04 UTC 
CI says "no occurrences", is this a valid bug?
Comment 4 Lakshmi 2019-11-01 07:34:11 UTC

> CI says "no occurrences", is this a valid bug?

This failure was originally associated with another bug. Since this is a separate issue later I filed this bug. Looks like no new failures are associated to this bug.
Comment 5 Chris Wilson 2019-11-01 16:14:24 UTC 
Should be happy now with a slight bit of extra leniency in the timeout for scheduling lapses.
