Bug Description

After upgraded to 17.04 from 16.10, my system cannot boot into the GUI anymore with kernel 4.10.0. I can boot it with the old kernel 4.8.0 from 16.10. When boot with 4.10.0 kernel, the system is crashed. I can see that ath9k caused it from dmesg.
Also this bug report is created with atk9k disabled so if there is anything missing, please ask so I could include it.

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

Once this bug is reported upstream, please add the tag: 'kernel-bug-reported-upstream'.
