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

I had a fully working linux system, just moved it from a thinkpad P73 to
P17, which is obviously a new architecture.
smpboot: CPU0: Intel(R) Xeon(R) W-11855M CPU @ 3.20GHz (family: 0x6, model: 0x8d, stepping: 0x1)

Both 6.4 and 6.6 start hanging a short time after boot in various ways.
If I can't get this new laptop working soon-ish I'm going to have to return it, but I'm indeed wondering 
what could be wrong.
Unfortunately the P73 straight died, so I can't go back and forth, but I
know both kernels and the entire user space worked fine on that system
before it just died.

Suggestions welcome
