[Dnsmasq-discuss] Infinite loop in IPv4 + IPv6 DHCP setup with 2.80 on aarch64

[Noel Kuntze]

Hello list,

I am encountering an issue with dnsmasq 2.80 on aarch64 (armv8 64 bit) wherein dnsmasq
infinitely loops sending its RAs. The configuration file and logs are following below this message.
The logs are produced when allowing dnsmasq to run for one second.

Kind regards

Noel Kuntze
