Thanks, Baptiste,

I can confirm that 21.02.0 branch now works as well. Here is the start of the kernel log:

My only issue left with OpenWrt right now is that if for some reason I need to restart dnsmasq without rebooting my router, it fails to load the hostnames I have set up on the device. The issue and a fix is described in FS#3090:
[[https://bugs.openwrt.org/index.php?do=details&task_id=3090|https://bugs.openwrt.org/index.php?do=details&task_id=3090]]

Can something be done about that?

Thanks for the great work and for putting up with users like me :)
Stay healthy and strong!
