Title:
[Dell Latitude E5550] Atheros Bluetooth [0cf3:e005] gone after suspend
Status in HWE Next Project:
Confirmed
Status in linux package in Ubuntu:
Confirmed
Bug description:
CID: 201406-15271 Dell Latitude E5550
After S3, the Bluetooth indicator will grey out (stays at the "OFF"
state), but rfkill show it's not blocked.
Even enable it by changing it to the "ON" state does not help, can't
find any device with it, hciconfig return nothing.
Error message could be found in the dmesg output:
[ 8996.779551] Bluetooth: Error in firmware loading err = -110,len = 448,
size = 1906
[ 8996.779570] Bluetooth: Loading sysconfig file failed
More important part is that after reboot, the Bluetooth will disappear
as it never exist, won't be listed in lsusb and dmesg.
