BUG overlayfs

gabriel3301

I just started to understand the intricacies of the internal structure of my favorite operating system - Linux.
But I had a problem that I cannot solve for a long time.

Error msg:

======== Card detection to detect SDIO card! ========
[ 1.382561] sdio: host isn't initialization successfully.

I am using kernel version 4.4 (aarch64).
As I understand it, the fact is that the workdir folder is not empty.
I have one very important question:
How can the bug be reproduced?
I tried to load all the memory - it didn't work, turned off the power (unexpected shutdown) and tried different methods, but it did not work. This error appears by itself, I would like to learn how to reproduce it in order to fix it myself in the future.

Thank you in advance.
