Install on eMMC Error

[Panda_Stonetree]

I have a IGEL UD3 M350C. Trying to install 24.04 onto its eMMC. Currently I have it installed via an external drive but I'd like to put it on the eMMC. This device does not have any other internal drive options.
I'm running into the below error, and can't access the eMMC. Any advice or suggestions would be helpful.

eMMC: SanDisk SDINBDG4-8G eMMC 8GB iNAND 7250 eMMC 5.1 WD/SD

I run into the same problem after upgrading a mini pc from Ubuntu 23.10 to 24.04. With the new kernel (6.8.0-31-generic), the system fails to boot not finding the SSD. With the old kernel (6.6.3-060603-generic) it still works. It seems that the new kernel is not working with the storage controller I have:

I was unable to find anything more about this except this forum post.
