Hi, It sounds like madness but "nvme controller is down" when I plug at the same time 3.5 jack headphones and USB headset to MB. This really scares me because I've never seen such an easy way to make a system broken. The most offensive thing is that in the kernel logs nothing strange is visible except for connecting a USB device and disabling the nvme controller.

Can you help me clarify what is really happening here? I can apply patches for verbose messages for understanding why block layers depend on USB and audio devices.
