Comment 10 for bug 2039926

Same issue with VERDE - (atombios and si_dpm) in both 6.5 and 6.8 series kernels on both radeon and amdgpu drivers

Whatever this is isn't just 1 or 2 places in the driver (and it's been occurring for several years)

Ubuntu Noble boot (dual W4100 quad-head cards), radeon driver - the amdgpu messages are similar
