root@E3000-test03:~# cat /proc/cpuinfo
system type : Broadcom BCM4716
machine : Linksys E3000 V1
iw - 4.9-1
iwinfo - 2016-09-21-fd9e17be-1
kernel - 4.4.71-1-3793d10ad2a0edb9d5642f8f862068f3
kmod-b43 - 4.4.71+2017-01-31-2 (open source driver, not the bcm binary)
Once the the 5GHz wireless interface is brought up an error occurs leading to a kernel panic and reboot. I know there are many gotchas with [[https://openwrt.org/docs/techref/hardware/soc/soc.broadcom.bcm47xx| BCM47xx]] and the Wi-Fi but I think the 5GHz should be working, and was working, in my mind, with previous OpenWRT releases
I reproduced on two different units to rule out an hardware issue.
How to reproduce:
Avoid doing it through UCI configuration... I had to recover the unit from the bootloop through serial failsafe mode (as I think network 192.168.1.1 + ssh does not work on E3000)
Below is the system log excerpt with the error, attach is the full bootlog
I think it is the same [[https://dev.archive.openwrt.org/ticket/20136|defect]] already identified on OpenWRT 3 years ago.
I gave it a try with kmod-brcm-wl and wl. here, the wl1 interface is even not available
root@E3000-test01:~# wl -i wl0 status
Not associated. Last associated with SSID: ""
root@E3000-test01:~# wl -i wl1 status
wl: wl driver adapter not found
With some hints in the boot log where only wl0 is found
Arduous:
