BCM4313: loading brcmsmac only possible manually

Hey guys,

I've got a problem with the brcmsmac module for my BCM4313: Wifi doesn't work when I load it at boot time, only removing it and inserting it manually helps. I know there was a bug report about a similar problem at https://bugs.archlinux.org/task/27938 but that didn't help me much...

Journalctl reads the following:

Jun 03 19:18:45 archbook kernel: cfg80211: Calling CRDA to update world regulatory domain

Jun 03 19:18:46 archbook kernel: brcms_module_init: register returned 0

What can I do about this?

As I already pointed out, adding it manually afterwards works without the slightest problem

Re: BCM4313: loading brcmsmac only possible manually

One thing i notice is:

Jun 03 19:18:46 archbook kernel: ieee80211 phy0: brcmsmac: Failed to find firmware usually in /lib/firmware/brcm

While the actual firmware is in /usr/lib/:

% locate brcm
[...]
/usr/lib/firmware/brcm

Re: BCM4313: loading brcmsmac only possible manually

Hi litemotiv, thanks for your advice! I placed symlinks for bcm43xx-0.fw and bcm43xx_hdr-0.fw and now loading at bootup works.
Hmm, strange though... why does modprobing manually look in /lib/usr/firmware/ while systemd-modules-load while uses /lib/firmware/?

Re: BCM4313: loading brcmsmac only possible manually

A lot of system paths have changed recently, i think this is fixed in the current packages in [testing] and will come to [core] in the near future.
