Testing with a powered USB 2.0 hub did not change the behavior,
unfortunately.
I'm beginning to think my WiLink8 module might be defective, or the driver
has some serious issue. Listening to an audio stream, using VLC, the radio
basically died:
[ 594.594514] wlcore: ERROR ELP wakeup timeout!
[ 596.130637] wlcore: ERROR ELP wakeup timeout!
[ 597.679125] wlcore: ERROR ELP wakeup timeout!
[ 599.815511] wlcore: ERROR timeout waiting for the hardware to complete
initialization
[ 601.902753] wlcore: ERROR timeout waiting for the hardware to complete
initialization
[ 603.993727] wlcore: ERROR timeout waiting for the hardware to complete
initialization
[ 604.002765] wlcore: ERROR firmware boot failed despite 3 retries
[ 604.098278] wlan0: failed to remove key (0, 04:bd:88:26:df:01) from
hardware (-5)
[ 604.327480] wlan0: failed to remove key (1, ff:ff:ff:ff:ff:ff) from
hardware (-5)
Unfortunately I'm out of time to debug, so back to USB WiFi for now :(
Regards,
Mike
