I think we should make an appeal directly to Intel. This problem is NOT
difficult to reproduce! If you turned off login security - I bet we
could make a shell script that launches VLC or something like it to
automate the entire process of testing a new kernel version... without
needing to touch a
It's great to see you keep trying this. For clarity, do you consider
this the same bug as https://bugzilla.kernel.org/show_bug.cgi?id=109051

kernel?
This problem is horrific in that the CPU / Motherboard watchdog isn't

I found a possible bug report that may help us. It specifically
identifies problems with Kernel 4.2 and hard system freeze.
https://bugs.freedesktop.org/show_bug.cgi?id=93214
Specifically note comment #11 on that bug report: "I added
"intel_idle.max_cstate=1" to the cmdline in hrub [grub]
Looking at the big picture: What concerns me most about this bug is the
way it deadlocks all of Linux. The console does not respond, there is no
normal crash dump, etc.
My thoughts are: We could try a non-Ubuntu kernel? One compiled from
source or another distro. And see if there are open bugs
Back to your very first comment / the title of this bug. How did you
identify the "drivers/gpu/drm/i915/intel_display.c:1743
vlv_wait_port_ready" in the crash? Are you able to get that driver to
be identified with each crash - or only sometimes?

Andrew (keen101): that pretty much confirms my experience reported in
comment #67 - that kernel 4.1.x is the newest one that doesn't deadlock
- and I'm on a different system from your Dell (Acer and HP systems,
pure Intel GPU and CPU).

Found a newer working kernel: Linux 4.1.23-040123-generic #201604281334
SMP Thu Apr 28 17:37:02 UTC 2016 x86_64 is GOOD! But
4.2.8-040208ckt9-generic fails (Ubuntu 15.10 kernel). Every kernel I
have tried that is newer, freezes on Netflix via Chrome in under 2
hours.

I tried the latest mainline kernel, 4.6.0-040600rc6-generic
#201605012031 SMP Mon May 2 00:33:26 UTC 2016 x86_64 -- it still freezes
in Netflix + Chrome (this time 20 or so minutes). I noticed my CPU fan
was idle / lowest state - but about 8 secons after the freeze the fan
went to highest speed.
Intel GPU drivers seem to be the common thread here. My Acer system
freezes hard with screen stuck and entirely unresponsive. It's an Acer
E1-510P-2671 with 8GB of RAM. Intel Celeron N2920 processor with Intel
HD Graphics (integrated graphics).
