[Lars Kumbier]

System fails to enter suspend mode on ubuntu 16.04 LTS (beta2) - did work on ubuntu 14.04 LTS.

Events:
* closing the laptop lid, or
* calling `sudo pm-hibernate` via terminal

Effect:
* Screen goes black
* System stays on, but no commands are acknowledged (mouse, keyboard, trying to switch to tty1 via CTRL+ALT+F1)

Expectation:
* System enters standby

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.6 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Tested with v4.6-rc1-wily (4.6.0-040600rc1_4.6.0-040600rc1.201603261930_amd64), bug is resolved there.

Lars Kumbier, the next step is to fully reverse commit bisect from kernel 4.4 to 4.6-rc1 in order to identify the last bad commit, followed immediately by the first good one. Once this good commit has been identified, it may be reviewed for backporting. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?

Please note, finding adjacent kernel versions is not fully commit bisecting.

After the fix commit (not kernel version) has been identified, then please mark this report Status Confirmed.

Thank you for your understanding.
