Description Paul Osmialowski 2024-11-18 10:53:26 UTC

Maybe it's not immediately bad (no observable problems yet), but any warnings in interrupts are always bad and make the system not trustworthy.

After inserting popular MSI graphics card (GeForce GT 710 based) newly purchased on Amazon, I'm seeing this in dmesg:

It's Gentoo Linux with Plasma and SDDM. I've tried two distribution (genkernel) kernels: linux-6.6.52-gentoo and linux-6.6.58-gentoo-r1, both with the same warning in dmesg.

Comment 1 Paul Osmialowski 2024-11-18 11:43:18 UTC

I've just made an accidental discovery: this does not happen when I'm using HDMI output only. And that's a huge degradation, as I'm so got used to work with two-monitor setup like this:

Comment 2 Artem S. Tashkinov 2024-11-18 13:37:37 UTC

Please check 6.12 and if it's still affected repost here:

https://gitlab.freedesktop.org/drm/nouveau/-/issues/

Comment 3 Paul Osmialowski 2024-11-18 16:45:17 UTC

Ah yes yes, I've unmasked 6.12.0-gentoo and it happens there too.

Comment 4 Paul Osmialowski 2024-11-18 16:55:22 UTC

As suggested, I've opened freedesktop issue: https://gitlab.freedesktop.org/drm/nouveau/-/issues/394

Comment 5 Paul Osmialowski 2024-11-18 23:52:49 UTC

I came across this page: https://bugs.mageia.org/show_bug.cgi?id=31695 and tried the workaround presented on it, I've created /etc/X11/xorg.conf as such:

Section "Device"
    Identifier "device1"
    Driver "nouveau"
    Option "DPMS"
    Option "NoAccel" "true"
EndSection


And the problem is gone.

Of course, this is only workaround, not a solution.

Comment 6 Joe Breuer 2025-03-10 19:42:43 UTC

I get a very similar thing with kernel 6.13.5, and an (OK, it's ancient) nVidia GeForce 8600 GT (G84):

irq 25 handler nvkm_intr+0x0/0x210 enabled interrupts
WARNING: CPU: 1 PID: 1355 at kernel/irq/handle.c:161 __handle_irq_event_percpu (kernel/irq/handle.c:161 (discriminator 1)) 
...

I also have some other diagnostics from nouveau in dmesg - 5 copies of this, about 12 seconds before the kernel WARNING:
nouveau 0000:01:00.0: fifo: DMA_PUSHER - ch 3 [sddm-greeter-qt[1199]] get 0000216004 put 0000216088 ib_get 00000007 ib_put 00000008 state 800081a4 (err: INVALID_CMD) push 00406040

I'll try the workaround suggested above; and take any findings on to the linked freedesktop issue.
