590.48.01 breaks Oblivion Remastered, brings kernel into broken state

[Midar]

NVIDIA Open GPU Kernel Modules Version

590.48.01

Please confirm this issue does not happen with the proprietary driver (of the same version). This issue tracker is only for bugs specific to the open kernel driver.

• I confirm that this does not happen with the proprietary driver package.
  (Not applicable, as there is only the open driver for the 5000 series - maybe remove that checkbox?)

Operating System and Version

Fedora 43

Kernel Release

6.18.7-200.fc43.x86_64

Please confirm you are running a stable release kernel (e.g. not a -rc). We do not accept bug reports for unreleased kernels.

• I am running on a stable kernel release.

Hardware: GPU

GeForce RTX 5800 Laptop

Describe the bug

When launching Oblivion Remasted and loading a save game, it freezes after no more than 5 seconds and the kernel module complains:

NVRM: Xid (PCI:0000:64:00): 109, pid=1023029, name=GameThread, channel 0x0000000b, errorString CTX SWITCH TIMEOUT, Info 0xcc008

It is not possible to close the game as it entirely hangs. Only kill -9 works. When restarting the game after kill -9, the kernel seems to be now in a weird state and it freezes in the menu almost immediately.

To Reproduce

Start Oblivion Remastered using Proton Experimental, load a save game.

Bug Incidence

Always

nvidia-bug-report.log.gz

It's impossible to run nvidia-bug-report.sh, as the kernel module seems to bring the kernel into such a broken state that nvidia-bug-report.sh immediately crashes the entire system.

Please let me know if there is anything else you want me to try or anything other than running nvidia-bug-report.sh.
