Description Marc Meledandri 2019-06-25 16:10:53 UTC
Created attachment 144635 [details] vbios.rom As of stable kernels 5.1.8 and 4.19.49, the GTX 260 fan runs at full speed after resuming from suspend. This behavior regressed as of commit 342406e4fbba9a174125fbfe6aeac3d64ef90f76 drm/nouveau/i2c: Disable i2c bus access after ->fini() https://lkml.org/lkml/2019/6/7/673 Reverting this single commit when building the respective stable kernels fixes the fan speed issue. $ lspci -nn -d 10de: 01:00.0 VGA compatible controller : NVIDIA Corporation GT200 [GeForce GTX 260] [10de:05e2] (rev a1) Discussion on Nouveau mailing list: https://lists.freedesktop.org/archives/nouveau/2019-June/032620.html

Created attachment 144637 [details] [review] Fix for Tesla i2c regression Hi! Turns out I actually have one of these GPUs in my drawer, so I was able to reproduce this issue with no problems. Could you verify that the following patch fixes your issue? If so, I'll add your Tested-by and send it out onto the nouveau ML

Hi! Thanks so much for the quick turnaround on this one. Great that you had a card on hand to test with. I can confirm that this patch applied against stable kernel 5.1.15 resolves the fan speed issue when resuming from suspend.
