Thanks for the detailed report.
smu7_powergate_uvd+0x23
pp_set_powergating_by_smu+0x15a
amdgpu_dpm_enable_uvd+0xc1
taskq_thread
POLARIS10 has UVD 6.3
If driver init fails the task gets removed by:
cancel_delayed_work_sync(&adev->uvd.idle_work);
uvd_v6_0_hw_fini
amdgpu_device_ip_fini_early
amdgpu_device_fini_hw
amdgpu_driver_unload_kms
amdgpu_driver_load_kms
amdgpu_attachhook
but your trace must occur before that gets cleaned up
smu7_powergate_uvd+0x23 is
/sys/dev/pci/drm/amd/pm/powerplay/hwmgr/smu7_clockpowergating.c:118
114 void smu7_powergate_uvd(struct pp_hwmgr *hwmgr, bool bgate)
115 {
116 struct smu7_hwmgr *data = (struct smu7_hwmgr *)(hwmgr->backend);

118 data->uvd_power_gated = bgate;
