Rick reported that his Pluggable USB4 dock does not work anymore after upgrading to v6.10 kernel. It looks like commitc6ca1ac9f4("thunderbolt: Increase sideband access polling delay") makes the device router enumeration happen later than what might be expected by the dock (although there is no such limit in the USB4 spec) which probably makes it assume there is something wrong with the high-speed link and reset it. After the link is reset the same issue happens again and again. For this reason lower the sideband access delay from 5ms to 1ms. This seems to work fine according to Rick's testing.
