What is reason of kernal crash? Unable to handle kernel paging request at virtual address

[tom_chou]

Hi,

I develop imx8mm customer board.

We have a question at system boot-up, that always reboot.

Does any one meet similar issue or can provide the direction about the cause of this issue?

[ 1.418800] Kernel panic - not syncing: netlink_init: Cannot allocate nl_table

But does it always end up panic in netlink? It feels like because of running out of memory then it crashes here as it could no longer allocate any memory for netlink.

Normally it happens during kernel init that if any init process fails it will be restarted and cannot be killed, eventually cause running out of memory and kernel panic.

It is not so easy to find out why, I would suggest starting from device tree.
