Can you try 'git bisect'? I'll hold off on releasing 4.9.y until this gets figured out.
After reverting this patch, network started works on arm32 x15 device. d7ba3c00047d ("net: phy: micrel: Restore led_mode and clk_sel on resume")
Does that also fix the hang during 'ip l'? (If the hang only occurred on the same systems that oops'd in the micrel driver, it could well be because the task that oops'd was holding the rtnetlink lock.)
Now 'ip l' works and the oops message is gone.

There may be some confusion since this patch was in 4.9.94 and we did not report this issue then. The way these failures presented themselves made them a bit subtle (we didn't get any hard failures, just some incomplete jobs - not an unusual occurrence on embedded boards) so we didn't notice them in the last release. It was only after Naresh manually investigated that this was discovered.
We'll think about how we can improve our process to make these much more obvious in an automated way.
