Same on Glymur CRD with next-20261013, GMU fw v5.2.38:

[    6.619232] platform 3d6c000.gmu: [drm:a6xx_hfi_wait_for_msg_interrupt [msm]] *ERROR* Message HFI_H2F_MSG_GX_BW_PERF_VOTE id 11 timed out waiting for response
[    6.629590] platform 3d6c000.gmu: [drm:a6xx_gmu_set_oob [msm]] *ERROR* Timeout waiting for GMU OOB set GPU_SET: 0x4
[    6.629750] msm_dpu ae01000.display-controller: [drm:adreno_load_gpu [msm]] *ERROR* gpu hw init failed: -110
[   14.795082] platform 3d6c000.gmu: [drm:a6xx_gmu_resume [msm]] *ERROR* GMU firmware initialization timed out

Dropping just the .clx_tbl/.limits_tbl from the 0x44070001 entry fixes it.

Tried on top of next-20261013, no change:
 - the QCOM_SCM_GPU_CLX_EN_REQ change
 - GENPD_FLAG_NO_STAY_ON on gpu_cc_cx_gdsc
 - modprobe.blacklist=msm and modprobe msm at ~90s, after all sync_state()
   calls are done

So on CRD it is not an ordering issue. The CLX/IFF_PCLX HFI messages are
all acked, then the first GX_BW_PERF_VOTE never gets a reply and the GMU
stays wedged after that.
