    BBBW kernel panic

    kiwibone

      Hello,

       

      I've recently got myself a Beaglebone Black Wireless. It gets a kernel panic every time I power it on.

      I have tried multiple SD card images, also tried disabling modules in uEnv.txt. The board is effectively bricked, I have not seen a single successful boot up.

       

      Here is what I get on the serial console:
