Hi, after upgrading to 4.4-166 on the linux-gru kernel (i am using a samsung chromebook plus) the device no longer boots arch linux. After clicking Ctrl-U at the boot screen, the screen goes black. Normally, after about 2 seconds (after the rockchip driver loads) the screen turns on and the boot process continues. However, after the upgrade, the screen simply does not turn on.
I had wiped my package cache at some point, so I didn't have an older kernel saved, so I extracted 4.4-164 from the linux-gru-latest image. After booting that kernel, however, wifi no longer worked, the wireless interface didn't even show up. I have reflashed the kernel several times to no avail on either version. Wifi still works fine in ChromeOS which is probably on a way older kernel.
I have been using alarm for a couple months and have done several kernel upgrades fine until now.
So, I am looking for either a new kernel version that boots properly, another kernel version that is saved in an archive somewhere (I counl't find a working package archive), or a way to fix wifi on the older kernel (I was using that kernel previously with wifi fine; but after upgrading and downgrading it has stopped for some reason).
