Hello everyone,
A BeagleBone black of mine seemingly crashes (syslogs have NULL filled areas) so I tried activating the kernel crash dump functionality so I can debug it/find the root cause. However when I test it and panic the kernel (via sudo sync; echo c | sudo tee /proc/sysrq-trigger), the crashdump kernel loaded also panics! So no dump is actually created.
I attaching the relevant kernel logs showing the panic but it seems it’s something related to udev:
[ 1.645589] r3 : c80f0030 r2 : 00000001 r1 : 00000030 r0 : c80f0000

does someone have some pointers towards what should I be looking at to fix it?
The kernel used is: 4.14.256-bone53 Sorry I’m not using the latest but it brakes some stuff and I’m not ready to make the jump.
Thank you!
