> 
> 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

> 
> [Fix]
> 
> Upstream commit addc33924 ("rtl_bt: Update RTL8851B BT USB firmware to

> 
> [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.
