I had never heard of this problem until upgrading to 16.10 yesterday.
Now my HP DV6000 is suffering from this exact problem, about 5 times in
less than 24 hours since the upgrade.

[Xbuntu 14.04, 14.10 and 15.04] Network manager stops working: iwl3945
0000:03:00.0: BSM uCode verification failed at addr ...; wlan0:
deauthenticating from... by local choice (Reason: 3=DEAUTH_LEAVING),
Status in network-manager package in Ubuntu:
From time to time, the system loses all wireles networks and kubuntu
network manager applet goes blank - not even one network is shown. All
wifi connections are broken. Rebooting fixes the issue, switching to
WICD on-the-fly enables to continue browsing without rebooting, so it
seems to be no hardware issue or iwl3945 issue.
What to expect: stable connections and flawless network managing.
What happens: so above.
Further informations about the system, the network configuration, the
package version can be found in the attachment, also parts of rsyslog
Interesting, according to some helpers, are the following lines:
dmesg: wlan0: deauthenticating from 02:26:4d:ac:8f:45 by local choice
