This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- zesty' to 'verification-done-zesty'. If the problem still exists, change the tag 'verification-needed-zesty' to 'verification-failed-zesty'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Kernel-packages] [Bug 1697027] Re: ath9k freezes suspend resume Ubuntu 17.04
I can confirm that the same issue occurs with kernel 4.12.0-041200rc4-generic and that the issue did not exist with Ubuntu 16.10. I do not know which kernel introduced the issue but immediately after upgrading to Ubuntu 17.04 I started observing the machine occasionally freezing upon resuming from suspend. I have just installed kernel version 4.12.0-041200rc4-generic and reproduced the bug. To reproduce the bug I usually need to suspend the system about five times. Most of the times suspend/resume does work just fine, and then occasionally it leaves the system in an unrecoverable state. Not sure if a specific state triggers the issue. It seems random to me. I have attached the dmesg output I obtained with kernel 4.12.0-041200rc4-generic. The issue seems to be exactly the same as with kernel 4.10.0-22-generic. Once the bug arises, I cannot file the report with apport as the machine is unable to use the network: $ apport-collect 1697027 ERROR: connecting to Launchpad failed: Unable to find the server at launchpad.net You can reset the credentials by removing the file /home/genovese/.cache/apport/launchpad.credentials Is there a way to collect the data with apport into a file and upload it later after rebooting the machine? ** Attachment added: "dmesg.4.12.0-041200rc4-generic" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1697027/+attachment/4893177/+files/dmesg.4.12.0-041200rc4-generic ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1697027 Title: ath9k freezes suspend resume Ubuntu 17.04 Status in linux package in Ubuntu: Confirmed Bug description: Description: Ubuntu Zesty Zapus Release: 17.04 What was expected to happen?

[Kernel-packages] [Bug 1697027] Re: ath9k freezes suspend resume Ubuntu 17.04
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 v4.12 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.
