This is with a proprietary codebase that I can't share, but I can help track it down if you can give me some pointers.

Do you have any clue what ioctl this is? I can't find anything in the kernel that matches. Is there interesting hardware involved?

Yep that would be it, there is a NVIDIA GPU attached that it is trying to initialise. Minimal repro:

#include <cuda.h>

int main()
{
  cuInit(0);

  return 0;
}

I don't need to debug the CUDA specific code (and certainly nothing that runs on the device), but it would be nice to still use the functionality of rr for the regular host code.
