Karma Shader Precompilation H22 July 19, 2026, 8:31 p.m.

We've fixed the error-message at the end of the (you could ignore that stuff anyway).
The fix will be out in the first daily-build.

It's repeating the same xx/548 whatever for the fourth time now. I'm pretty sure it didn't do this in earlier versions.

Plus, on Linux the compile took only 23 minutes, on Windows 11 was looking to take 10+ hours.

regarding these two, we're still looking into it and with the aim to have it fixed by the first daily, thanks for testing + reporting back.

Karma XPU — cudaErrorIllegalAddress (Xid 31) on dual RTX 409 July 14, 2026, 7 a.m.

Sorry for the noise — the issue is probably too specific to my setup to be reproducible on different machines.

No worries, its good to raise this kind of issue regardless.
One thing, what happens if you roll back the driver? to perhaps a 595 range?

Another note, it happens on windows as well, so I guess it is drivers incompatibility with XPU and only road to take is roll back drivers to old versions I assume?

ah, sorry I thought you said windows was working fine

**Question:** Is driver 610.x validated against Houdini 21.0, and is there a known issue with it (or with nvidia-open modules specifically)? Happy to provide a repro scene, nvidia-bug-report.sh output, and exact repro steps to support if useful.

We're not aware of any issue, but have not done extensive testing yet.
Repro scene + exact repro steps would be great thanks. As simple scene as possible is ideal.

thanks
