I don't know what is triggering the kernel BUG, but you have an error
in your udev rules. The pertinent file is
/etc/udev/rules.d/70-persistent-net.rules. Any rule that renames a
wireless device should look like the following:
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", \
ATTR{address}=="00:90:4b:d2:1f:cd", ATTR{type}=="1", \
KERNEL=="wlan*", NAME="wlan0"
The ATTR{address} should match the MAC address of the device, but the
ATTR{type}=="1" is really important as it keeps the master device from
being renamed, which is the usual cause of the presence of a name like
wlanX_rename.
