It is not an absolute deal breaker but we are looking for the Thinkpad model providing the best suspend/resume support under FreeBSD. I've scoured the Internet and have essentially learned that the T520 and the T530 might be the best bet. > > Can others confirm this is still the case under FreeBSD 10.1?

Before suspend I need to switch kern.eventtimer.timer from HPET to LAPIC (this enabled by default). With HPET it does not resume. 2. With Composite enabled in X11 I need patch [1] to avoid some screen garbage after resume. Without Composite all works fine. [1] http://lists.freebsd.org/pipermail/freebsd-x11/2013-October/013727.html
