F15 BCM43224 stopped working after update

A year ago I set up the BCM43224 wireless on my laptop. It has worked fine after each kernel update until the most recent. I have seen many threads on here about bcm43224 support, but I think my problem is different.

I have blacklisted bcma, and kmod-wl was working until the most recent kernel update. I suspect an update to something else (other than the kernel and kmod-wl) may be causing the problem, but I can't figure out what.

Some details:

$ uname -r

$ lsmod | grep wl
wl 1960208 0

$ dmesg | grep "wl\|eth"

$ iwlist eth1 scan

I have no idea why the scan is failing. I tried compiling the broadcom-wl driver from source instead of using kmod-wl, and I get the same problem: nothing unusual in the logs and the scan is failing.
