Yes, I did. I did not manage to find the commit that caused it.

Maybe Karl has an idea. This image is known to work [1]:

glaubitz@suse-laptop:~> file uImage-git.gz
uImage-git.gz: u-boot legacy uImage, Linux-6.5.0-rc2, Linux/SuperH, OS Kernel Image (gzip), 4416616 bytes, Mon Jul 17 14:17:35 2023, Load Address: 0X80001000, Entry Point: 0X80002000, Header CRC:
0XBA69203A, Data CRC: 0XD097D603
glaubitz@suse-laptop:~>

It boots fine with:

usb reset ; fatload usb 0:1 0x89000000 uImage-git.gz ; pmb ; bootm
