Use debug on log verbosity to prevent the crash.

@asvio I'm compiling from your sources. Why are there two 24.10 branches? nbg7815-24.10-nss and nbg7815-24.10.0-nss, what's the difference?

1126

24.10.0-nss will not have any update. It is a fixed branch base on on openwrt 24.10.0 release tag.

24.10-nss branch will be update following oficial 24.10 branch so this branch will have patches to improve stability and to correct problems that appear with use, but it will not incorporate new functions that may affect stability.

@RaylynnKnight Could you add NBG7815's device page https://openwrt.org/inbox/toh/zyxel/nbg7815_armor_g5 to https://openwrt.org/toh/hwdata/zyxel/start ?

https://openwrt.org/toh/hwdata/zyxel/zyxel_nbg7815_armor_g5 has existed since 2024/06/19. So I'm not sure what your are asking me to do.

You've forgotten to add the device page link

The link you posted is incomplete and contains only basic info. Compare it with the device page link I posted

OK I thought you were talking about the Data Entry page, not the Device Details page. I've now created the Device Details page using the template and copied data over from your inbox page into the appropriate sections. I left your inbox page so that you can check to see if I missed anything. Once you've confirmed that the Device Details page contains all appropriate data then we can delete the inbox page.

It's not my inbox page, it's OpenWRT's original device page for NBG7815.

The new device template doesn't look good enough to me. I copy/pasted the original device page. If this is against OpenWRT's plans for the device pages, please revert it.
