At a ThinkPad T420 w/ a 32 bit stable Gentoo Linux and a started X11 server an attempt to s2ram results in a blank scree, a gloomy blinking power button and no syslog message or something helpful . If the system is booting w/o X11 then s2ram works.

s2ram in 3.10.5 works - and FWIW in 3.11-rc5 s2ram is fine.

Can you run 'git bisect' to track it down to the offending patch?

Also, does 3.11-rc5 work for you?

thanks,

Ick, I forgot that I patched the 3.10.X directory with:
https://patchwork.kernel.org/patch/2827512/

patching that out now let s2ram works again in 3.10.6

(but s2disk is broken in 3.10.6, however I do not know, since when, nevertheless a different issue)
