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. -- ================================================================= :: Brandon Wandersee :: :: brandon.wandersee@gmail.com :: ================================================================== 'A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.' - Douglas Adams ==================================================================
