Thx for the report. Not my area of expertise, but this a bit similar to
the symptoms that Marc Payne (now CCed) reported a while ago:
https://lore.kernel.org/linux-bluetooth/ZsTh7Jyug7MbZsLE@mdpsys.co.uk/

Hao Qin (now CCed, too) posted a patch to fix this:
https://lore.kernel.org/all/20240822052310.25220-1-hao.qin@mediatek.com/

But then things apparently stalled and my inquiry for a status update
was ignored.

Nicholas, maybe wait a day or two if somebody with more expertise
replies with something more concrete. If not it might be good to check
if ccfc8948d7e4 is the culprit for you as well and/or if the patch
linked above helps.

Ciao, Thorsten
