Please update the subject of the first post to include the network device chipset, for example:I've booted the older kernel - and now IPv6 works. So there is some issue, probably in the newer drivers for this network card, which is the absolutely horrible MT7922. Somehow, it filters out router advertisements. Time to do some more debugging and probably file a report.
Appears this is a known issue: https://bugs.launchpad.net/ubuntu/+sour ... ug/2049303
