Package: src:linux Version: 6.12.107-1 Severity: minor Tags: upstream Dear Maintainer,
CONTEXT ======= I upgraded this machine from Debian 11 to Debian 12 to Debian 13. While looking into a Wayland freeze on the same machine (Debian bug #1147096) I noticed this error message, which is unrelated as far as I can tell but is new since the upgrade. WHAT I OBSERVE ============== On a GeForce 210 (GT218, Tesla), nouveau logs an error-level message on every boot with the 6.12 kernel: nouveau 0000:01:00.0: drm: failed to create ce channel, -22 nouveau 0000:01:00.0: drm: MM: using COPY for buffer copies Booting the same machine on linux-image-6.1.0-52-amd64 does not print it. I have not noticed any misbehaviour I could attribute to it, and the second line suggests buffer copies still work. I am reporting it because it is an error that was not there before, on hardware that is presumably not tested much any more.
