Subject: Re: Thinkpad P17 keep hanging in ipv6_addrconf addrconf_verify_work / netlink in 6.4 and 6.6

So, I thought that maybe my custom built kernel had options that somehow
made P17 unhappy, and went to a stock debian kernel.
It's not really looking better with that kernel unfortunately :-/

Still seems unhappy with networking, first wireless and then ethtool.
Adding wireless lists to Cc just in case
