Thanks for the report. My current plan is to retire all of sa1100 by merging my board file removal series for v7.5-rc1, so it should be gone from linux-next soon but still be available for the LTS release (whether that is 7.3 or 7.4). Hopefully Dmitry can spot an obvious fix for the regression, otherwise a revert is probably best so we can leave collie working in the LTS kernel and not spend much work on that. Arnd
