Message-ID<wTZv3-3yi-3@gated-at.bofh.it>
Package: firmware-brcm80211
Version: 20161130-4
Severity: important

Dear Maintainer,

   * What led up to the situation?

Normal debian system upgrade:
2018-11-13 08:57:19 upgrade firmware-brcm80211:all 20161130-3 20161130-4


   * What was the outcome of this action?

After next boot the WLAN interface is no longer usable. The system reports:

Interface wlp4s0 is not available as a result.


   * What outcome did you expect instead?

The firmware to be loaded correctly and the WLAN interface to be usable as
usual.


I tried the packages from stretch-backports (20180825+dfsg-1~bpo9+1) as well as
latest firmware blobs from linux-firmare git, but only a downgrade to
firmware-brcm80211:20161130-3 allowed the firmware to be correctly loaded.

Is this still reproducible with current Debian Testing (upcoming
Bullseye)?
