So we either need to find the cause (likely a missing backport) through some other way or maybe revert the culprit in the 6.1.y series. Jeremy, did you try if the latter is an option? If not: could you do that please? And could you also try cherry-pikcing c7eaf80bfb0c8c ("Bluetooth: Fix hci_link_tx_to RCU lock usage") [v6.6-rc5] into 6.1.y helps? It's just a wild guess, but it contains a Fixes: tag for the commit in question.
I gave it a try, and sadly I'm still hitting the exact same bug when I cherry-pick the patch you mentioned on top of 6.1.y (at tag v6.1.87).
Thanks for trying, is there any other patch that looks like a good candidate?
