Hi there. I just installed Arch on a Macbook Pro late 2013, and I can't get the wireless card working. The following error is logged whenever I try to connect with wpa_supplicant, scan with wifi-menu, etc:

[ 50.465231] ---[ end trace 6a3281ba2d2fadea ]---The process then hangs for a few more seconds afterwards. I'm using the broadcom-wl driver from the AUR, and everything is up-to-date.
Wireless was working fine on a previous install on the same machine about a month ago. Any thoughts?
PS. I won't be able to reply for about a week, sorry. Thanks in advance!
