"mmc0: Controller never released inhibit bit(s)" or "mmc1: Timeout waiting for hardware cmd interrupt."
After flashing the daily image (2021-10-08) on a SSD in a USB enclosure, I was surprised to see that the kernel was complaining about what it seems the SD card controller, quite often (once every few seconds).
This manifests either by "mmc0: Controller never released inhibit bit(s)" or "mmc1: Timeout waiting for hardware cmd interrupt.", depending on the boot.
It does not seem to affect the usage, but I do not use SD cards on this setup (for now).
I was wondering it might be a firmware-related issue since I found some occurrence about this on Rasperry Pi Foundations forums for a few devices on RP OS.
Anyway, I prefer to report it in case, someone would struggle with this, in the current state of the Raspberry Pi images.
