Reminds me of Bug 346519, but that's supposed to be fixed, and the backtace isn't exactly the same.

Did you remember to reboot after installing the NVIDIA driver? If not, can you reboot and try again?

Comment 2 Colin J Thomson 2022-04-26 19:21:31 UTC

Just FYI I have had no such issue on this F36 Box with the nVidia RPM's from rpmfusion. However I do run Plasma etc from zawertun's COPR so it is right up to date. Maybe it has already been fixed?

Operating System: Fedora Linux 36

Graphics Processor: NVIDIA GeForce GT 1030/PCIe/SSE2

Comment 3 Thomas Pasch 2022-05-01 12:09:40 UTC

I tried to reproduce this several times on the machine that was effected. However, it was not possible. You could be very right that happened after installing the nvidia driver but before rebooting.

(Nvidia on my 'NVIDIA Corporation TU106 [GeForce RTX 2060 Rev. A] (rev a1)' seems to be delicate on F36. It works the the rpmfusion packages for 510.47.03, but only with a old (F35) kernel. But that's a different story.)

Comment 4 Nate Graham 2022-05-02 18:48:44 UTC

Cool, I suspect that's what happened.

You've always gotta reboot after installing or upgrading your NVIDIA drivers, or else lots of weird things will happen.
