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- xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed- xenial'.
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.

Previously two workaround commits were added in the Xenial kernel, 8a034f97a28dba62026343eef7992766c91273a7 and f21d12781c88413aec7ee44983f05b1cdf90662f, to mitigate this issue. The original report can be found at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1712746 . Now that a fix has been merged in mainline, it's time to revert the workaround and apply the fix: commit c61cfe49f0f0f0d1f8b56d0b045838d597e8c3a3 Author: Limin Zhu <limin...@marvell.com> Date: Thu Nov 30 14:22:34 2017 +0800 mwifiex: cfg80211: do not change virtual interface during scan processing (1) Change virtual interface operation in cfg80211 process reset and reinitilize private data structure. (2) Scan result event processed in main process will dereference private data structure concurrently, ocassionly crash the kernel. The cornel case could be trigger by below steps: (1) wpa_cli mlan0 scan (2) ./hostapd mlan0.conf Cfg80211 asynchronous scan procedure is not all the time operated under rtnl lock, here we add the protect to serialize the cfg80211 scan and change_virtual interface operation.
