[Bug 2049938] Re: Bang & Olufsen Cisco 980 loses connection on 6.5 generic kernel
@Aaron，As just talked, can you help to double check it? Besides the kernel, are there any other aspects that can impact the result? Our account rep wonder if you need a meeting with the customer or you need the HW to debug the issue? From the dmesg, it is ThinkPad X1 Carbon Gen 9.

All though you state that there is no difference in the two the LE functionality of the headset works on the OEM kernel and does not work n the Jammy generic kernel.
