Georg Seema is bringing up a Cudy P5 (also IPQ5018). Without this patch the board hangs during boot; with it applied it boots reliably. He found the patch on his own while debugging that hang, and gave the tag on the OpenWrt pull request that carries it: https://github.com/openwrt/openwrt/pull/24653 Tested-by: Georg Seema That makes three IPQ5018 boards from three vendors - TP-Link Archer AX55 v1, GL.iNet GL-B3000 and Cudy P5 - where gating the CMN block bus clocks after probe kills the boot, and holding the reference fixes it. I am not repeating the earlier arguments here. The bisection of the fatal access is still on my list and I will come back with v4 and a corrected explanation once I have named the register and the code path, rather than before. Thanks, Stanislaw
