Could not boot Linux from mmc

Hi:
I am having very weird problem which I have not able to figure out (yet). I have one of the first generation up-board which runs Debian with patched kernel 4.9 (https://github.com/emutex/ubilinux-kernel/commits/upboard-4.9). When I try to use different generic kernel version (5.19 amd64) I am getting weird error during the boot:
mmc0: unrecognised CSD structure version 0
mmc0: error -22 whilst initialising MMC card
Now if I boot Ubuntu with kernel version 5.19 from usb flash drive I can see the mmc and I can access it.
Any ideas what could be the issue?
Board: AAEON UP-CHT01/UP-CHT01, BIOS UPC1BM0S 06/04/2016
Ram: 4GB
MMC : 32GB
Thanks

It turned out the debugging of sdhci was on which was braking the module.
