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 -- Łukasz Walewski <ljw@xxxxxxxxxx>
