Adding clk_ignore_unused lets the Cubie A7S reach an interactive initramfs shell. I reused the September 21 uninstrumented comparator: v7.3-rc1 plus the four single-divider patches, CCU v4, the seven pinctrl patches, and the minimal test DT, with only ahb_cpus_clk marked CLK_IS_CRITICAL. The Image, DTB and initramfs were byte-identical to that earlier comparator; the only boot-argument change was adding clk_ignore_unused. Without the flag, that comparator stopped producing serial output at "clk: Disabling unused clocks". With it, the confirmation run recorded: [ 1.263452] clk: Not disabling unused clocks [ 1.292364] Run /bin/sh as init process [ 1.526500] mmc0: new high speed SDXC card at address 544c Commands issued after the shell prompt returned the expected readiness and completion markers. No panic, oops or SError appeared in the capture. The RAM-only run was followed by a guarded 120-second power-off recovery, which restored the vendor kernel and eMMC root. This narrows the second failure to the path bypassed by clk_ignore_unused, but does not identify an individual clock: the flag also bypasses the runtime-PM acquisition and traversal before the per-clock disable calls. I therefore still cannot add a Tested-by for v4 as posted. Assisted-by: Codex:gpt-6 Regards, Enzo
