Comment 3 Martin Peres 2019-04-01 13:09:40 UTC
This bug is only happening on iclb2.

As explained in https://bugs.freedesktop.org/show_bug.cgi?id=110271, this might indicate a HW issue with the pre-production machine, as opposed to the platform.

Keeping the priority high because of the potential high customer impact (as per Daniel's comment), in order to investigate potential fixes quickly.
Comment 4 Martin Peres 2019-04-12 13:18:07 UTC
As per comment https://bugs.freedesktop.org/show_bug.cgi?id=110271#c6, this seems to be a real issue, and both of these bugs could be an outcome of it. Closing this bug as duplicate.
