Hmmm, Louis (which already was in the CC) posted a patch with a Fixes: tag referencing that commit more than a month ago: spi: omap2-mcspi: Ensure that CS is correctly asserted when switching from MULTI mode to SINGLE mode https://lore.kernel.org/all/20240506-fix-omap2-mcspi-v2-1-d9c77ba8b9c7@xxxxxxxxxxx/ Unless I'm missing something, that patch did not make much progress since then. But I wonder if that might help. Louis? FWIW, this thread starts here with João problem description: https://lore.kernel.org/all/20240612170030.3qatttsgrwjg2m5s@joaog-nb/ Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page.
