Bang & Olufsen Cisco 980 loses
@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. Thanks.
