Not sure what do you mean.

The issue is that the ioctl for media status (which invokes the mii bus) races
with a currently running tick (ure_tick for example).

So the MII bus code runs in a single thread always, but one invoked by ioctl
and another one by the tick callback race between each other sometimes (and it
is not clear why, as both code paths use the same lock...)
