Hi all,

An update:

* Using suspend/resume with non-VESA kernel and syscons appeared
unstable. After 3-4 successful resumes, the notebook hung up and then
rebooted.

* However, using vt + retry patch (I succeeded in porting vt to
10.0-RELEASE) proved out to be very stable! I suspended/resumed
more than 30 times over last 7-8 days, without any problem (without
shutting down).

* Following ray@'s advice, I filled this PR:
http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/188833
I'll try (following ray@'s offline advises) to improve the retry hack
until things get fixed.

Thank you, people, for your work and for making modern notebooks fully
functional with FreeBSD! It's a very great pleasure to have a FreeBSD
notebook with suspend/resume (many thanks to ray@ for his work on vt,
which made this possible), good wifi support (iwn driver from HEAD
works flawlessly), 3D desktop with Mac-style tabbing (i915kms.ko works
without a glitch) and skype video calls (thanks to CentOS-6.5 porting
team).

Ivan
