Bug description:
[SRU Justification]
[Impact]
There are multiple stability issues for RTL8851B.
Issue-1:
After disabling BT and leaving it idle for a period, manually turning on the
RTL8851BE will fail.
Issue-2:
Failed to probe Bluetooth USB interface after resumed from suspend. There may
be
either failure to read device descriptors:
usb 1-14: device descriptor read/64, error -71
or tx command timeout:
Bluetooth: hci0: Opcode 0x2041 failed: -110
Bluetooth: hci0: command 0x2041 tx timeout
[Fix]
Upstream commit addc33924 ("rtl_bt: Update RTL8851B BT USB firmware to
0x048A_D230").
[Test Case]
$ checkbox-cli run
com.canonical.plainbox::suspend/suspend_advanced_auto
[Where problems could occur]
This updates opaque firmware blobs, so it could bring further stability issues
and/or power consumption changes.
[Other Info]
While RTL8851B is only supported in oem-6.5 and linux/mantic >= 6.4, only
jammy
and mantic are nominated for fix.
