Yes.  The behaviour I described is, so far with 15-20 tries, consistent.

I confirm that I see the similar behavior on my T520 ThinkPad, Sandy Bridge
system.
FreeBSD rogue 10.2-PRERELEASE FreeBSD 10.2-PRERELEASE #1 r284698: Mon Jun

It has been working flawlessly since Adrian's ACPI update. As of now, it
suspends fine, but it won't resume. I get a fan spin-up, but the power LED
continues to pulse, indicating it is suspended and the logs show nothing
after the suspend.

Shall I start a binary hunt for the culprit? It will likely take a few
kernel builds as my last known working kernel was in late May.
