Thank you. For what it’s worth I was able to grab a dump after setting that sysctl. It looks like this maybe the culprit?
panic: _sx_xlock_hard: recursed on non-recursive sx gmbus @ /usr/src/sys/modules/drm2/i915kms/../../../dev/drm2/i915/intel_iic.c:362 Since it is to large for posting here. I will include a link to the entire dump on pastebin if anyone is interesting in looking at it. http://pastebin.com/mzS5svy8 In addition I did a little further testing to narrow down the issue. 10.1-RELEASE WORKS 10.2-RELEASE WORKS I recall trying a 10.2-STABLE image that crashed as well. I can tell you for sure that the following releases all the way back to August have the issue for CURRENT. FreeBSD-11.0-CURRENT-amd64-20150804-r286285-memstick.img FreeBSD-11.0-CURRENT-amd64-20150917-r287930-memstick.img FreeBSD-11.0-CURRENT-amd64-20151001-r288459-memstick.img FreeBSD-11.0-CURRENT-amd64-20151119-r291085-memstick.img If there is an archive of older images for CURRENT I would be happy to try those to help further narrow down where things broke.
