Hi,
I'm using kernel 4.14.79.
Apart from the problem I'm facing in previous thread,
I'm also facing crash for mmc0 in SDHCI omap driver.
We have SD card on mmc0 and EMMC on mmc1. Whenever I boot using EMMC and SD card is not connected, I face these crash logs after random time since boot.

And these logs keeps coming untill I restart the board.
How can I fix this problem?
Thanks,
