Comment 5 for bug 1697027

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?
