We have just noticed that since Linux v6.9 was released, that if we

The old code upgraded the limits to the PAGE_SIZE for this case after
issunig a warning. Your driver probably incorrectly advertised the
lower max_segment_size. Try setting it to 64k. I would have sent you
a patch for that, but I can't see what mmc host driver you are using.
We are using the sdhci-tegra.c driver. I don't see it set in there, but
I see references to max_seg_size in the main sdhci.c driver.
Thanks,
