dmesg

very strange problem occurred.

if amdgpu vce used to encode video with ffmpeg, xhci_hcd starts to loosing packets (mouse hangs for few milliseconds, usb sound card sound crackling), and after some time used usb ports stopping to respond at all, so i need to connect hub into another port (if reconnected to same port, device is not detected). dmesg in attachment.

looks like it was bios bug, after recent bios update problem disappeared.
