With Intel AC9560, follow this scenario and can't turn on bt since. 1. turn off BT 2. then suspend&resume multiple times 3. turn on BT Get this error message after turn on bt. [ 877.194032] Bluetooth: hci0: urb 0000000061b9a002 failed to resubmit (113) [ 886.941327] Bluetooth: hci0: Failed to read MSFT supported features (-110) Remove msft from compilation would be helpful. Turn off msft would be also helpful. As per Intel's comment, For AC9560, in JSL the hw_variant is 0x13. In GLK, the hw_variant is 0x11. can't use hw_variant to filter for AC9560. Only AC9560 encounter this issue, so add a reject table to disable msft for AC9560.
