Public bug reported:
When using the hwe kernel, my laptop is unable to receive multicast
packets. Running avahi-browse -a produces an empty output. Switching to
linux-generic-6.11 resolves the issue (avahi-browse -a shows all the
services in my LAN as expected), so I know it's an issue with the kernel
and not a userspace problem.
