Some context: This is the first panic in stable/14 I've experienced in ... a long time. It was on my "daily driver" laptop; I had set it up for this morning's updates (I track stable/14, head, and stable/15, and update all installed ports, daily on this laptop, as well as a build machine and a couple of other laptops). The laptop itself is old (Dell shows that the machine with this service tag first shipped 17 Oct 2014), and made up of parts from several Dell Precision M4800s, and has recently started treating "poweroff" as "power cycle" for reasons that are not clear to me. When I get up, then, I expect to be able to check on the status of the most recent "git fetch", prepare for the next one (I have things set up to do 2 of them overnight -- a relic of how I used to do things with svn, which was a relic of how I used CVS (& CVSup), then start fetching distfiles while I build world.... I was, therefore, rather surprised to see the xdm login banner when I arrived at my desk. :-} As the machine had been set up & left unattended, there wasn't much processing going on, and it appears to have come back up in time to do the daily backup to a mirror SSD successfully. And I expect to migrate from stable/14 to stable/15 shortly after 15.0 is announced, so there may be less incentive (& interest) in poking at this one (than if it had happened in stable/15 or head -- or on a newer machine).
