Hi,
As you may know, suspend/resume has been broken on Lenovo x220 for a
long time now, see :
http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/174504
I have been able to do a suspend(S3)/resume operation in text mode (it
works, but console stays dark at resume, I had to connect through ssh ;
also, resume hangs if X is started with i915kms.ko loaded) and collect
the following verbose logs :
