Comment # 8 on bug 1190608 from Bunte Katze

@Takashi Iwai 

So we have a huge step here:

I was able to recompile the nvidia kernel module for 5.14.5-1.1.gfdb6afd:

`zypper in -f kernel-default-devel=5.14.5-1.1.gfdb6afd
nvidia-gfxG05-kmp-default`

With `prime-select nvidia` I could switch to the newly installed module.

When I rebooted (5.14.5-1.gfdb6afd-default, now with nvidia support),
everything ran perfectly!

No more boot hang, and the messages following "usb: port power management may
be unreliable" are back to normal:

Sep 17 21:03:44 felicity kernel: usb: port power management may be unreliable
Sep 17 21:03:44 felicity kernel: xhci_hcd 0000:01:00.2: xHCI Host Controller
Sep 17 21:03:44 felicity kernel: xhci_hcd 0000:01:00.2: new USB bus registered,
assigned bus number 3
Sep 17 21:03:44 felicity kernel: xhci_hcd 0000:01:00.2: hcc params 0x0180ff05
hci version 0x110 quirks 0x0000000000000010

So 5.14.2-1-default seems to have a regression to 5.14.1-1-default, while
5.14.5-1.1.gfdb6afd (or earlier, like 5.14.3 or .4 possibly) fixes that.
