For me everything's fine after yesterday's kernel update. Shutdown and suspend work as expected. So this bug seems to have been fixed indeed, for the Qualcomm Atheros QCA9377 chip at least.
The current kernel (4.13.0-17-generic #20-Ubuntu SMP Mon Nov 6 10:04:08) appears to be unchanged from the one I previously tried to install from proposed, so I guess the boot problems that I encountered where due to some mistake of my own. -- 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/1724317 Title: Shutdown hangs / no standby - possible Wifi-bug in the kernel Status in linux package in Ubuntu: Confirmed Bug description: The Shutdown-process hangs. After about two minutes the following message is displayed: Oct 17 18:47:06 Kahlan kernel: [ 363.170588] INFO: task kworker/u8:2:186 blocked for more than 120 seconds.

This message repeates itself. If I am lucky, my laptop shuts down after some time. Also standby does not work. I think my wifi-adapter causes this problem. With Ubuntu 17.04 or Suse 42.3 I cannot reproduce this problem. I found a bug report in the Arch Bug System (https://bugs.archlinux.org/task/55872 In my laptop I have also a Qualcomm Atheros Adapter. Perhaps the linuxkernel has a bug?
