Now we got a feedback from the latest linux-firmware (20190726) and
surprising the result was negative.  The dmesg after the cold boot is
found at:
  https://bugzilla.suse.com/show_bug.cgi?id=1142128#c26

The kernel is 5.2.3, so it should be new enough.

If anything else needed (or something missing), let us know.
