Another crash instance

[cwichmann]

I haven’t seen anyone post this specific crash (attached it below) but I am hoping its is resolved in the new kernel or fixed somewhere else. Seen a few instances of the kernel panic with address access though it seems to have stared only after bringing eth0 up.

I am using the kernel/image shipped with the board (though same behavior with a self compiled one).

Question… Is the newer kernel 4.11 and 4.12 more stable with the expressobin or are they crashing frequently as well?

At this point, the board is not usable for any prototyping.

Here is the crash…
