Hi all,
In the last month or so I've found that suspend is failing on my Dell XPS 15 9550 laptop. The log below indicates there's a problem with the brcmfmac driver for the Broadcom WiFi chip.

Sep 13 13:31:27 archlinux kernel: rfkill: input handler disabledIf I have the time, I'll have a look at the linux-firmware package's changes over the last few months, but if anyone has advice or a solution, I'd greatly appreciate it.
EDIT: I tried force-restarting the brcmfmac module before suspending, and the suspend worked; however, after a reboot, this method has no effect.
