Hi

I have just bought my first BBB wireless. out of the box I was getting kernel panic sporadically. I upgraded to the latest debian and still the kernel crashes after max 5min of startup.

here is the uart log:

Any Suggestions, is that a HW issue?

Hi

I have just bought my first BBB wireless. out of the box I was getting kernel panic sporadically. I upgraded to the latest debian and still the kernel crashes after max 5min of startup.

here is the uart log:

ebian@beaglebone:~$ connect [ 136.074614] Unhandled fault: external abort on non-linefetch (0x1028) at 0xf9e00028

I am replying, because I like the details of this question.
However, you probably want to upgrade.

That error may be caused when clocks are not enabled.
In that case my guess would be a missing kernel module.

It is a bit strange that it happens after five minutes. But it is also mentioned that it is not always the same time period.
Is there a timed job that triggers it?

The technical reference manual of the an33xx could tell you what component is located at address 0xf9e00028. That could also give a hint as to why the call is made only after a few minutes.

As mentioned above you probably just want to update the software to the latest version. If you are using a unadapted beaglebone it is most likely that the problem is already fixed.

It you are already on the latest release, provide some details about any hardware modifications you made.
That way there might be some more hints coming.

Best,
Hugo
