Package: linux-image-amd64
Version: 5.10.136-1
I recently bought a new monitor the cheap HP M24f 2D9K0AA and connected
via HDMI port to the NVIDIA GeForce GT 630 card.
When I switch twice virtual terminal (CTRL-ALT-F2 - CTRL-ALT-F7) it
happens that the kernel pollutes the VT screen with this error message:

-----------------------------------------------------------------
Looking at the kernel source 5.10.136 x86_64 I think that the error
message is in the drivers/gpu/drm/nouveau/dispnv50/disp.c file at line 869:
...
ret = drm_scdc_readb(nv_encoder->i2c, SCDC_TMDS_CONFIG, &config);
if (ret < 0) {
NV_ERROR(drm, "Failure to read SCDC_TMDS_CONFIG: %d\n", ret);
return;
}
...
----------------------------------------------------------------
I know nothing about Linux driver. Could anybody provide me a fix or
some hints to avoid this message?
TIA

-----------------------------------------------------------------
Looking at the kernel source 5.10.136 x86_64 I think that the error
message is in the drivers/gpu/drm/nouveau/dispnv50/disp.c file at line 869:
...
ret = drm_scdc_readb(nv_encoder->i2c, SCDC_TMDS_CONFIG, &config);
if (ret < 0) {
NV_ERROR(drm, "Failure to read SCDC_TMDS_CONFIG: %d\n", ret);
return;
}
...
----------------------------------------------------------------
I know nothing about Linux driver. Could anybody provide me a fix or
some hints to avoid this message?
TIA
