"Oddness" in head since around r343678 or so

I run and track stable/11, stable/12, and head (from separate slices --
no VMs involved) on my laptop; among other things, this permits some
degree of comparison among them.

The laptop is configured to run xdm; while running stable/11 or
stable/12, there's a period of about 5 seconds after xdm's login banner
shows up before either the mouse or keyboard responds.

Up to a few days ago, head was the same, but as of about last weekend (I
think), that period is about 40 seconds while running head.

I realize that's a little ... lacking in specificity, and I apologize
for that.  And while I noticed it a few days ago, I hadn't actually
timed it until this morning.

Information, including verbose dmesg.boot copies and a log of uname
outputs, may be found from the page at

Here's a list of the uname outputs for head over the last several days:
