Suspend is working but i am unable to > resume again. You haven't said .. is this trying to suspend and resume from text or graphics mode? As you see on the Wiki page at your [1], some machines work ok with one but not the other. Others will - or used to - work if switching X to text mode before suspending, where that's still possible. My much older X200 suspends 100% on 9.x, text or X, and on test memstick boots of 10.2 and 10.3, from text mode at least. But not from an 11.0-R memstick boot - it suspends fine (text mode, VT) but resumes sans video; 'Live CD' boot can't onestart sshd (RO /var) so I've not yet pursued it. Mine's a far older machine, most likely a different issue to yours and I'm not chasing that here, just pointing out that mine has worked fine for years without tuning on earlier releases, including (before trying with latest X) on 10.3-R memstick boots with fairly thorough testing. > Actually i am interested in having an exchange of experiences which kernel > modules and configs are needed and which one should be avoided to > successfully enable suspend/resume. > > I already found "Suspend/Resume on FreeBSD-Wiki" [1].

Odds seem to favour video card issues. You could browse freebsd-acpi@ and freebsd-mobile@ archives; not sure about "s" model but various T460 appear over the time. Happy hunting. cheers, Ian
