The hangs occur between minutes and hours after booting and there is no information found related to them in kernel message buffer. I found the above commit by doing bisection between 4.1.0 and 4.2-rc1 and reported it to intel-gfx mailing list: http://lists.freedesktop.org/archives/intel- gfx/2016-January/084203.html I tested that these hangs occur with 14.04 LTS using latest linux-generic-lts-wily (4.2.0-23-generic) kernel exactly as with any kernel beginning from 4.2-rc1 up to 4.4-rc8. I'm now writing this bug report running 4.4-rc8 with patches from the above commit removed because 4.2.0-23-generic just hanged while I was trying to send report.
