SLEEP is 0xf, the bitwise OR of (AT86RF2XX_STATE_RX_AACK_ON | AT86RF2XX_STATE_TX_ARET_ON) equals 0x1f, so this state transition to PLL_ON was wrongly triggered when leaving sleep for any mode which has 0x1X as its state code. The symptom is a hang in the transceiver driver thread because the transceiver is not listening to state transition commands while in sleep mode.

sleep for any mode which has 0x1X as its state code. The symptom is a
hang in the transceiver driver thread because the transceiver is not
listening to state transition commands while in sleep mode.
I hit this bug when using ifconfig to set some options while the transceiver was sleeping.
