    I flashed the arch image on the website on my Udoo QUAD.
    I succeeded in working with wlan0 with wpa_supplicant and nmcli; my dekart dk-38t worked with pcscd too.
    I did a pacman -Suy this morning and I updated all the packages.
    After that wlan0 disappeared and dmesg doesn't detect if I plug in/off my dekart sim reader.

    Code:
    [alarm@alarm ~]$ sudo ifconfig wlan0 up                                                                                                               
    wlan0: ERROR while getting interface flags: No such device
    Code:
    [alarm@alarm ~]$ lsmod

    Could you help me to manage this problem? Should I reflash the previous image?

    USB seems to be broken since 4.8.x with Arch Linux ARM on the UDOO.
    I fixed this temporarily by downgrading to the last 4.7.x kernel using:

    pacman -U /var/cache/pacman/pkg/linux-armv7-4.7.6-1-armv7h.pkg.tar.xz

    In my /etc/pacman.conf I set this to prevent upgrading the kernel for now when upgrading the system:

    [options]
    IgnorePkg = linux-armv7

    I originally reported the problem to the Arch Linux ARM forum but my post didn't get much attention so far there:
