2. Linux Kernel keeps crashing for me at boot. This happens after switching WiFi status by hardware-switching it off and on (and off, ...) at my HP-tm2 This Bug is reproduce-able and i can "fix" it by completely powering off my notebook and wait a few seconds (no power cable, no battery)
I also reported this bug at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1056105 3. Keywords: brcms_c_wait_for_tx_completion kernel 4.
