The thunderbolt controller in Ice Lake and Tiger Lake is different to previous generations in a few fundamental ways which breaks some of bolt's fundamental assumptions:
1) the host switch associated with a domain has a stable uuid
2) the host switch associated with a domain has vendor/name attributes
A consequence of 1) is the accumulation of stale domains in the store. A consequence of 2) is that generation detection is broken.
I upstream bolt 0.9.1 release should fix all those issues.
