eMMC frequently not found by Linux kernel (especially on low battery)
#2
Hmmm, I thought it was just me. I made a mistake with my eMMC, so I booted Manjaro off SD card. Except while booted to Manjaro on SD card, my eMMC was not found. Could not even get the normal eMMC commands to re-enable the device to work some of the time.

Now I have noticed that booting Manjaro off eMMC was not reliable, and tracked it to U-Boot. Based on another user's forum post, I used the latest default Debian U-Boot files on my eMMC. That has made booting Manjaro off eMMC quite reliable. Perhaps I need to do the same for my Manjaro SD card.

It almost looks like a race issue.

Maybe the eMMC takes longer to stabilize than the SD card?
And maybe the U-Boot files don't wait long enough after initialization?
