My T450 does resume now with an current CURRENT(r333291), but
unfortunately i do not know why...
I tried to track down the phenomenon. I saw that the kernel seemed not
to be involved in this matter, since the old BE equipped with a new
kernel was able to resume. I cloned the BE capable of resuming and
startet copying userland-stuff from the "default" BE to this BE. Stuff
was like bin/sbin/lib/libexec folders from / and /usr and so on. It
stayed able to resume! Then i made an installworld/installkernel of
r333291 into this BE, (but without mergemaster)! Even after this it
stayed able to resume! Then I backed up the /etc folder of my "default"
BE (which was not able to resume) and copied the /etc from the old BE to
"default". After this, "default" was also able to resume again!
Long story short, i'm happy my machine resumes again, but i do not have
a clue why...
P.S.
I'm useing drm-stable-kmod, drm-next-kmod did not work for me.
