Bug#1110880: general: Kernel 6.12.38-1 - Black screen on resume from suspend with NVIDIA (regression from kernel 6.1.140-1)

Dear Maintainer,

After a recent distribution upgrade, my system no longer resumes from suspend. The screen remains black, requiring a hard reboot.

This is a regression, as the system suspends and resumes correctly when I boot with the older kernel.

Steps to Reproduce:

    Boot with kernel 6.12.38-1.

    Log into the XFCE desktop.

    Suspend the system (e.g., by closing the laptop lid or running systemctl suspend).

    Wake the system.

Expected Result:
The desktop/lock screen should appear and be usable.

Actual Result:
The display remains black and unresponsive.

Working Configuration:
This issue does NOT occur on kernel 6.1.140-1.

System Information:

    Graphics Card: GeForce GTX 1050 Ti

    NVIDIA Driver Version: 550.163.01-2

I have attached the full journalctl log from a failed boot (journalctl -b -1). Thank you for your time.
