Ubuntu 16.10 suspend problem on Dell Latitude E5470

[boniek00]

I have a suspend problem with my laptop Dell Latitude E5470 on Ubuntu 16.10. When I suspend the system, CPU fan starts spinning and doesn't stop, even the rest of devices seem to be suspended (power button is blinking as in suspend mode). I've just upgraded BIOS to the latest version 1.9.4, but it didn't help. I googled for similar issues, but didn't find any. Any ideas?

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 v4.9 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.

I have this problem from the begging. First I installed Ubuntu 16.04 with kernel 4.4.43. I also tried kernels 4.6.* and 4.8.*. None of them solved my problem. I upgraded BIOS to the latest version 1.9.4. I run various hardware diagnostic tests, but found nothing.

I've just tested on kernel 4.9.0-040900rc1.201610151630. Unfortunately bug is still there.
