Hi there!
With the Linux 4.9 series (upto 4.9.50), the GPU hangs upon resume from
disk (hibernation) on a laptop with Intel Broadwell graphics.
I filed a bug [1] and got to know that it has been already fixed [2].
Would it be possible to have this patch included in the Linux 4.9 LTS
series?
Thanks,
Aaditya

BR,
Jani.
I looked through the bug report which contains the fix [1], and it seems
that the patch was applied to the Linux 4.9 series and then reverted due
to regression with Skylake [2][3].
Since it works on my Broadwell based system, I'll keep on using it; the
expert opinion is that it cannot be easily backported without more
changes [4].
Thanks,
Aaditya
