Just updated my T520 yesterday, and I get the same behavior with the
same machine here. Suspend is fine; resume fails. It seems to get a bit
farther along in the resume process if i915kms isn't loaded, though I've
got no way to really measure that. I've tried a GENERIC kernel, clean
source tree and empty src.conf, to no avail.
Several MFCs in r280434 from a couple weeks ago touched a whole bunch of
suspend/resume stuff. That might be a good place to start digging.
