Peter, did you look into this? Anyway: To be sure the issue doesn't fall through the cracks unnoticed, I'm adding it to regzbot, the Linux kernel regression tracking bot: #regzbot report: https://lore.kernel.org/all/20240401144424.1714-1-mike@xxxxxxxxxxxxxx/ #regzbot introduced: 1cb63d80fff6c4 #regzbot title: net: Bluetooth: firmware loading problems with older firmware #regzbot ignore-activity Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr That page also explains what to do if mails like this annoy you.
