The wifi driver is not enabled by deafult when booting.

Not sure the wifi driver are you using? the one stored in
drivers/net/wireless/rtl8187b/ with CONFIG_RTL8187B? if it is. you can
try to enable it when booting via putting the following lines
into /etc/rc.local:

wifi_interface=`find /sys/class/rfkill/ -name "state"`
[ -n "$wifi_interface" ] && echo 1 > $wifi_interface

Good idea.

Seems "blank" is handled in X(relative to the SM712 video driver), but
the backlight is controlled in the backlight driver(a platform subdriver
for YeeLoong), it will be hard to merge them together.

So if you want to save the power when the screen is in active, please
configure the relative action via kpowersave or gnome-power-manager.
they will really change the backlight of the
screen(/sys/class/backlight/backlight0/brightness) and save power for
you. and if you want to shut it off, configure the time for entering
into standby mode automatically.

Tried install Epiphany on my standard debian system, and run it with
wireless, not made my kernel panic.

Not sure, Added address@hidden in the CC list, hope he can explain
why.

Could you please try to
remove /etc/udev/rules.d/70-persistent-net.rules?

and reboot the kernel. and then it should work as wlan0 for you.

Have explained it in another thread, I have set the deafult brightness
level in the backlight subdriver when initializing, will fix it in the
next version.

Yup, this is a known problem, I only found it when with the new EC
version(such as PQ1D26, please check the version via
"cat /proc/cmdline"). I have tried to resume the brightness in the
kernel when resuming from Fn + F2, but it not works. So, perhaps EC does
some BAD jobs there, will check it later and will try to fix it in
kernel space.

did you try kexec?

Thanks very much for your feedbacks ;)
