[Bug 1575467] Re: [Dell Inspiron 3451] WARNING: CPU: 1 PID: 1297 at /build/linux-lts-utopic-vy2yyy/linux-lts-utopic-3.16.0/drivers/gpu/drm/i915/intel_display.c:1743 vlv_wait_port_ready+0x126/0x170 [i915]()
Still using 4.7.0-994-generic. It again isn't freezing. And hasn't in
several weeks. That's not to say that there is not still a problem
there, but it's the best kernel i've tested so far (other than the old
3.16). I think i only had freeing problems when my CPU was hot and my
fan was running high.
But if you can appeal to the intel programmers directly then by all
means be my guest. I can't bisect this on my own, and others in those
other bug reports have hinted that bisecting will do no good for this
issue anyway since there is not enough information about what is
actually causing it. Bad Intel code? Maybe. Seems a plausible
explanation to me. Especially since i had seen some mac bug reports of
freezing around the same time and Macs use intel chips too.

[Dell Inspiron 3451] WARNING: CPU: 1 PID: 1297 at /build/linux-lts-
Status in linux package in Ubuntu:
Status in linux source package in Xenial:
After upgrading from stock Ubuntu 14.04 to 16.04 my laptop
consistently freezes up and is unresponsive to keyboard or mouse. The
only way is to do a hard shutdown. I'm usually in a browser when this
happens, and often watching a video or two. It seems to happen more
often in Google Chrome than Firefox, but it happens with both. It has
happened at least once with no videos loaded. I haven’t observed it
freeze / hang when I’m not in a browser, but that's mainly what i use
my laptop for, so that's where most of my time is spent.
