I have this bug now. After reboot through 30sec, or 1 - 5 min - wi-fi down, with "failed to wakeup the MAC Chip" log. Same as after resuming, or on/off wi-fi by hardware or software button. ======== Wireless-Info START ======== System-Info ~~~~~~~~~~~~~~~~~~~~~~~~ stager-Satellite-L40 3.13.0-36-generic i686, Ubuntu 14.04.1 LTS, trusty CPU : Intel(R) Celeron(R) M CPU 520 @ 1.60GHz Memory : 993 MB Uptime : 14:05:06 up 4 min, 2 users, load average: 3,01, 1,91, 0,78 lspci ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 02:00.0 Ethernet controller [0200]: Qualcomm Atheros AR242x / AR542x Wireless Network Adapter (PCI-Express) [168c:001c] (rev 01) Subsystem: Askey Computer Corp.
