Comment 6 for bug 1859592

@mizzao that sounds a lot like my "solution" comments/2 indeed. However, during hot reboots on my dual boot setup, the Bluetooth DID work in Windows for me, but not in Linux. For Linux, a cold boot was required.

So I am inclined to believe that the Linux Bluetooth driver puts the Bluetooth hardware in a certain state that persists across hot reboots but doesn't affect the Windows driver from successfully interacting with the Bluetooth hardware.

I believe this to be a software bug where a certain state or signal from the Bluetooth hardware is misinterpreted by the Linux driver, causing it to stop working.
