(Thank you!)


The system is a Tongfang GK5CP0Z / XMG Neo 15 Early 2019 with NVIDIA RTX 2060.
I am using it with an external HDMI monitor. HDMI is only available in nvidia
mode, so I use prime-select to choose nvidia over intel.


Nvidia 470.63.01-43.1 is in use.

Kernel 5.14.1-1-default boots and runs perfectly.
Kernel 5.14.2-1-default fails to boot.

Kernel parameters (as copied from grub.cfg):

root=/dev/mapper/system-root  ${extra_cmdline} resume=/dev/system/swap
acpi_osi=! acpi_osi=Linux acpi_os_name=Linux acpi_rev_override=1
nouveau.modeset=0 nouveau.runpm=0 pcie_aspm=force drm.vblankoffdelay=1
scsi_mod.use_blk_mq=1 mem_sleep_default=deep mitigations=auto



Reproducible: Always

Steps to Reproduce:
1. Boot into zypper post snapshot after installing updates yesterday
2. Kernel 5.14.2-1-default starts booting
3. Prints twice ���������xhci_hcd: can't change power state from D3cold to D0 (config
space inaccessible)���������
4. Prints some other USB-related messages (see photo)
5. Freeze
Actual Results:  
Freezes.
No reaction of caps lock LED.
No reaction of virtual terminal hotkey (Ctrl+Alt+F1 - F12)
Can only hard-reboot by holding physical power button.


Expected Results:  
Kernel 5.14.2-1-default should boot just the same as 5.14.1-1-default does.

I tried booting the broken kernel (5.14.2-1-default) from its zypper post
snapshot by appending an additional boot param
`systemd.unit=multi-user.target`, but that made no difference at all. Same
freeze, same messages.

Journalctl does not seem to contain any of the frozen boots.
