Since bumping from 5.3.x to 5.4-rcX I have seen a bluetooth failure on all Amlogic SoC boards that I test with, using a range of different Ampak (Broadcom) SDIO modules. The following is from a board with BCM4359 wireless/BT (SDIO):

VIM3:~ # dmesg | grep -i Blue
[    5.594409] Bluetooth: Core ver 2.22
[    5.594500] Bluetooth: HCI device and connection manager initialized

[    7.944140] Bluetooth: hci1: command 0xfc18 tx timeout
[   16.050803] Bluetooth: hci1: BCM: failed to write update baudrate (-110)
[   16.050808] Bluetooth: hci1: Failed to set baudrate
[   18.184134] Bluetooth: hci1: command 0x0c03 tx timeout
[   26.077475] Bluetooth: hci1: BCM: Reset failed (-110)

Kernel defconfig:

Kernelci Amlogic images ( are showing the same "Frame reassembly failed (-84)” error.

This sounds similar: but modules will use hci_bcm not hci_qca.

Any ideas?
