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).
