Comment 27 for bug 2009136

To go further wiyh the last remarks, fdcc4c22b commit (https://github.com/torvalds/linux/commit/fdcc4c22b7ab20e90b97f8bc6225d876b72b8f16 is just the addition of a new device hw caps (PCI_DEVICE(0x1002, 0xab30). I doubt it can be the culprit.

I don't understand how the bisect did identify it as the source of the problem. Except if there was some kind of error when patching the ubuntu kernel package to mimic it.

By the way I am also impacted with:
> Baffin HDMI/DP Audio [Radeon RX 550 640SP / RX 560/560X] [1002:AAE0]
(lshw -numeric -class multimedia)
so device 0x1002,0xaae0
