I am also seeing problems with bluetooth in .39-rc4+

The same error happens If I just try a hciconfig hci0 up after boot (without replugging the adaptor).

CONFIG_BT_HCIBTSDIO=m
CONFIG_BT_HCIUART=m
CONFIG_BT_HCIUART_H4=y
CONFIG_BT_HCIUART_BCSP=y
# CONFIG_BT_HCIUART_ATH3K is not set
CONFIG_BT_HCIUART_LL=y
CONFIG_BT_HCIBCM203X=m
CONFIG_BT_HCIBPA10X=m
CONFIG_BT_HCIBFUSB=m
CONFIG_BT_HCIVHCI=m

and bluez-4.91 is installed

Ideas?
