I have been running 6.30.223.248+bdcom-0ubuntu1 on trusty 14.04.1 LTS for several weeks.

I applied the patch suggested by Andre yesterday, and haven't seen any kernel crashes yet. However, I am still seeing occasional (once per hour approx) loss of connectivity. A typical syslog extract is below:

Feb 2 23:47:12 bacchus wpa_supplicant[1287]: message repeated 25 times: [ wlan0: CTRL-EVENT-SCAN-STARTED ]
Feb 2 23:48:50 bacchus wpa_supplicant[1287]: wlan0: WPA: Group rekeying completed with 00:12:0e:54:e9:a4 [GTK=CCMP]
Feb 2 23:49:12 bacchus wpa_supplicant[1287]: wlan0: CTRL-EVENT-SCAN-STARTED
Feb 3 00:03:12 bacchus kernel: [ 3848.216125] ERROR @wl_notify_scan_status : wlan0 Scan_results error (-22)
Feb 3 00:07:12 bacchus kernel: [ 4088.258526] ERROR @wl_notify_scan_status : wlan0 Scan_results error (-22)

I have just checked the syslog and the error was also being logged prior to applying the patch. I wonder whether this error is relevant to this bug - sorry if it isn't.
