[MacBookAir6,2] Resumes immediately after suspend

[Jamon Camisso]

Based on https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1311724 I am opening this bug to tackle the issue of a Macbook Air that resumes immediately after suspending.

I have the exact same symptoms as those described in the first bug. The first suspend on battery power works without any issues. After that, even trying the 2x pm-suspend method doesn't work.

Here's an excerpt from dmesg showing the suspend:

Something that seems notable regarding the policy min/med/max policy in in /sys/class/scsi_host/host1/link_power_management_policy when managed via powertop:

If I try to toggle ' Enable SATA link power management for host1' after a suspend, powertop throws an error accessing the policy and shows 'null' in its output.

[Joseph Salisbury (jsalisbury)]

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.8 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.

[Jamon Camisso (jamon)]

I've had a go with linux-image-4.8.0-040800rc3-generic_4.8.0-040800rc3.201608212032_amd64 and the behaviour is the same, suspend immediately wakes up.

I also tried last week with linux-image-4.7.0-040700-generic_4.7.0-040700.201608021801_amd64 and it was present there.

Marked as confirmed and tagged as requested.

Please let me know if there is any more information that I can gather.

[penalvch (penalvch)]

Jamon Camisso, could you please provide the missing information from https://wiki.ubuntu.com/DebuggingKernelSuspend ?

[Ketil (ubuntu-rytmisk)]

I have the same problem on a Macbook pro retina. It works sometimes after a reboot, but always fails again after the first suspend.

Ketil

[Balint Reczey (rbalint)]

Same on Debian with 3.16.36-1+deb8u2

[penalvch (penalvch)]

Ketil (ubuntu-rytmisk), it will help immensely if you filed a new report with the Ubuntu repository kernel (not mainline/upstream) via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.

For more on why this is helpful, please see https://wiki.ubuntu.com/ReportingBugs.

[Ketil (ubuntu-rytmisk)]

Ok. I'll do my best. Here I follow the instructions from https://wiki.ubuntu.com/DebuggingKernelSuspend
1)As described above. The Macbook seems to suspend when closing the lid and then wakes again which is shown by the apple on the back och the lid lightning up

2) Closing the lid (but even doing it through the shut down menu in mate and unity)

3) See 2

4) Attached

The rest follows.

Ah - thanks. I tried to do the last thing from the wiki: sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend" and my computer just died. I had to hold power like forever before it would reboot...

Ketil (ubuntu-rytmisk), apologies for my confusing you. Please perform the instructions noted in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1616214/comments/8 , versus post attachments/comments in this report.

[Ketil (ubuntu-rytmisk)]

Isn't this bug a dubplicate: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1638788

Ketil

[Ketil (ubuntu-rytmisk)]

Here is more info obviously.

When I tried to run "echo XHC1 > /proc/acpi/wakeup" - it suspended correctly
