Is this limited to emmc or does it also happen with the micro-sd or wlan possibly? If the issue is emmc related, do you have mmc-pwrseq-emmc configured in the dts? > I'm able to reproduce on the IDK574x evaluation board (where the emmc is powered > at 3v3) with vanilla kernels. OK, looks like only am5729-beagleboneai.dts has configured mmc-pwrseq-emmc. > I had to revert all commits related to "PM runtime functions" [1] and "card > power off and enable aggressive PM" [2] from kernel 5.16 to use the emmc again > on both boards. OK, this sounds like power sequence related when the emmc gets idled.
