The cover said a job had signalled completion with its output buffer never written, all 48 channels 0x80, and that across 102 induced resets in nine runs it appeared only on the arm without 1/13 and 2/13. None of that is what you reported. Your table is 12 + 8 + 12 + 13 = 45 resets, two passes per kernel, and you wrote that the race did not manifest in the 45 on either kernel, with the oracle 48/48 on both arms. The 0x80 is ours: on RK3576 a fresh shmem BO is zeroed and teflon's readback adds 0x80, so an output buffer that was never written reads back as a uniform 128. I carried our own signature onto your RK3588 run, which never reported it. The patch text is the part that was right, and it is the only form of your result I will use: 45 induced resets across three cores, the domain dropping every time with no MMU message on either kernel, so this is not rocket-wide. You were careful to say your protocol could not settle whether a genuinely hung block behaves differently. I turned a bounding result into a reproduction. Jiaxing
