Can you please share a log with 'thunderbolt.host_reset=0 thunderbolt.dyndbg' on the kernel command line in a kernel that it doesn't work? This should make the behavior match 6.6.28 and we can compare.
Maybe the best thing would be: * 6.6.28 w/ thunderbolt.dyndbg * 6.6.29 w/ thunderbolt.dyndbg thunderbolt.host_reset=0
