No wifi after kernel update

I was having intermittent screen flickering, so I ran a `pacman -Syu` last night (I last updated on October 19), and now, after rebooting, my wireless adapter isn't appearing (`ip link` only lists loopback and my wired Ethernet adapter).

It shows up in `lspci -k`, but there's no "kernel driver in use" line:

02:00.0 Network controller: Qualcomm Atheros AR9462 Wireless Network Adapter (rev 01)
	Subsystem: Foxconn International, Inc. AR9462 Wireless Network Adapter
	Kernel modules: ath9k

Here's the output from dmesg.

Re: No wifi after kernel update

What was the kernel version without the issue?  Please post the kernel messages from a boot without the issue for comparison.
Is the system a chromebook?

Re: No wifi after kernel update

https://bugs.archlinux.org/task/64302 you also have some weird stack trace and looks like gsmi is loaded, try blacklisting gsmi

Yes, this is a Chromebook. Things are working properly after blacklisting gsmi.
