This failure occurred only once CI_DRM_5855_full (1 week, 5 days old) and this failure in CI bug log was captured under Bug 108767 which is incorrect and unrelated.
Comment 3 Arek Hiler 2019-04-15 12:31:25 UTC
This seems like a test deficiency. We are polling on udev monitor FD in anticipation of an events. According the the log linked in the previous comments we get EAGAIN (11), but we do not retry.

Moving to IGT.

We already retry when we get EAGAIN, but then eventually give up. So the EAGAIN errno is kinda expected.

The timeout right now is 1 second, which really should be enough to deliver an uevent. Maybe the box is totally overloaded or something like that.

It seems that we haven't seen this bug for a while now. Can we close this one?

This issue occurred only once CI_DRM_5855_full (2 months, 1 week old). We can close this issue if this failure doesn't appear in the the next 3 weeks.

Dropping the priority to Low as the reproduction rate is very low.
