            Bug ID: 219895
           Summary: amdgpu spamming log [drm] scheduler comp_1.0.1 is not
                    ready, skipping and becoming slow
           Product: Drivers
           Version: 2.5
          Hardware: AMD
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: kontakt@sandberg-consult.dk
        Regression: No

somewhere between 6.9.8 and 6.12.9 (also impacts 6.12.12, 6.12.19) it began
spamming the kernel messages like this:

[267433.487654] [drm] scheduler comp_1.0.5 is not ready, skipping
[267433.487786] [drm] scheduler comp_1.0.1 is not ready, skipping

[267433.497161] [drm] scheduler comp_1.0.5 is not ready, skipping


(and many many more).

sometimes it also spews this:

allthough thats far from all the time.

old installation used linux-firmware-20240909 with kernel 6.9.8, and newer
where it fails tried with linux-firmware-20250109 and linux-firmware-20250211
on 6.12.9+6.12.12+6.12.19.

the system has two gpus, one:
07:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Baffin [Radeon RX 550 640SP / RX 560/560X] (rev cf)

which is the offending, and is a 560, and another (in case its relevant,
non-offending):
0a:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi
22 [Radeon RX 6700/6700 XT/6750 XT / 6800M/6850M XT] (rev c1)

it seems to mostly be triggered when a monitor powers off, but once thats
happened, it seems to keep spamming quite regularly, sometimes stopping,
sometimes not.

I should note that when its in this state, its also slow to read the sensor
readings using lmsensors, the following block:

amdgpu-pci-0700
Adapter: PCI adapter
vddgfx:        1.10 V  
fan1:             N/A  (min =    0 RPM, max = 3500 RPM)
edge:         +27.0°C  (crit = +94.0°C, hyst = -273.1°C)
PPT:           9.23 W  (cap =  48.00 W)
pwm1:            128%
sclk:         562 MHz 
mclk:         300 MHz 

usually goes so fast that it returns instantly, but when its throwing these
errors, it takes ~1sec

FTR, here's the follow up:
