Thanks for the reports!

Ben also added a bug in bugzilla[1], let's use that one for tracking
(I'll mark Sergey's as a duplicate).

This is a know issue and our PHY team is already working on it
internally.  I don't have much more details at the moment, but I'll
update the bugzilla entry as soon as we know more.
