Subject: firmware-iwlwifi 20180825+dfsg-1 breaks bluetooth on Intel 8265
Package: firmware-iwlwifi
Version: 20180825+dfsg-1
Severity: important
I've been having problems with my new Intel wireless; I think I've actually got two problems here, one with 802.11x being unusably slow and one with bluetooth, so I'm doing my best to separate them into two different bug reports. This is the bluetooth one. I saw there were a couple of other "bluetooth not working" bugs but from a quick look through them none seemed to specifically apply to the 8265 so I felt it warranted a separate report.
Long story short, bluetooth broke on this machine some time ago (my logs don't go back far enough) but I didn't notice at the time since bluetooth doesn't get used very much on this machine. Suffice to say that some time ago bluetooth stopped working - hci0 was never properly initialised. In dmesg I would get messages like the following (only showing blue|firm lines for the sake of brevity):

Specifically the absence of the firmware beng loaded, and the following errors; 
    Bluetooth: hci0: command 0xfc05 tx timeout

On tracking back through the changelogs I saw that firmware-iwlwifi_20180825 included new bluetooth firmware for the 8265; I downgraded to firmware-iwlwifi_20180518-1_all and now bluetooth initialises correctly again, dmesg|egrep 'blue|firm' from the latest boot below:

Thanks, closing it.

Nothing is ever a complete failure;
it can always serve as a bad example.
