Hello,
our CI spotted this error on resume. It is not systematic, and it is
possible that this is not a new issue from 7.2.
Does it rings any bell?

Based on the log, the PHY initialization is failing during resume. I'll set
up a platform on my end to see if I can reproduce this issue consistently.
BTW, is this occurring on the i.MX8QM MEK board? What's the frequency of
occurrence in CI (failure rate)?
Best Regards
Richard Zhu
