This may be related to the fact that this is the second time I'm disabling UCSI on sc8280xp and apparently I used the same patch Subject last time so they end up in the same thread on lore: https://lore.kernel.org/lkml/20240608114529.23060-1-johan+linaro@kernel.org/ Bjorn has picked up this effective revert for 6.10 now, but I still figured I'd mentioned this to you in case you want to add it to the tracker and/or see what can be done to your scripts to avoid having regressions like this fall through the cracks in the future.
