Heh.. I out-delayed you. :-)
Dmesg: hotplug-in 3726 into 6145 , and the unplug, finally plug again

Heh.. failing PMP READs. Doesn't look like there's anything else to do
than disabling it. Will post a patch.
..
No kernel timestamps there, but I do wonder if somehow
the driver is polling too soon for the PMP?
I wonder if a short delay in there, before issuing the PMP read,
might help (or not)?
