Hi,
I am using the latest Lubuntu 16.10 with fairly recent kernel
ljw@hideo:~$ uname -a
Linux hideo 4.8.0-30-generic #32-Ubuntu SMP Fri Dec 2 03:43:33 UTC 2016 i686 i686 i686 GNU/Linux
on an old Toshiba laptop (Satellite Pro U200) equipped with an Intel PRO/Wireless 3945ABG adapter
ljw@hideo:~$ lspci | grep ireless
02:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
The wireless network crashes once in a while with no apparent reason with the following log entries:
Dec 18 17:23:42 hideo kernel: [94900.863133] iwl3945 0000:02:00.0: loaded firmware version 15.32.2.9
Dec 18 17:23:42 hideo kernel: [94900.913626] iwl3945 0000:02:00.0: BSM uCode verification failed at addr 0x00003800+0 (of 900), is 0xa5a5a5a2, s/b 0xf802020
Dec 18 17:23:42 hideo kernel: [94900.913633] iwl3945 0000:02:00.0: Unable to set up bootstrap uCode: -5
This problem has been reported several times on different mailing lists and community portals all over the Internet, nevertheless I was not able to locate the right fix for it.
The workaround suggested elswhere (restarting the network-manager when the problem occurs) works with my setup.
Could you please suggest the solution to the problem? Alternatively, where should I file the bug to get it fixed?
Thank you very much in advance,
Lukasz Walewski

Instead of restarting NM, you can "pkill -TERM wpa_supplicant" or
something, which will do the same thing but just bounce the wifi rather
than everything. Or 'rmmod iwl3945; modprobe iwl3945'.

Thanks, but that is just another workaround. I am interested in fixing the problem, i.e. getting the driver not to crash at all, rather than playing around with it crashing every now and then.

Yeah, I know. Just pointing out that people often use a huge hammer,
when a much smaller hammer will do.
