Public bug reported:
The driver for Broadcom BCM4350 works fine using the stock brcmfmac
driver, except when going into suspend or hibernation. On resume it will
crash and only a reboot seems to fix it.
After much chagrin and trying various driver packages (like the wl
driver) without any success (lots of complaining about firmware, etc in
dmesg), I managed to get the stock brcmfmac driver working perfectly by
instructing the pm-* set of commands to unload and subsequently load it
when doing any kind of power management.
Essentially, some package should execute
echo 'SUSPEND_MODULES="brcmfmac"' | sudo tee -a /etc/pm/config.d/config
for this to work for most Dell XPS machines.
Hardware info attached.
Expected: wifi driver to keep working after suspend or hibernation
Actual: brcmfmac driver crashes.
