Hi WayneWWW,
we applied all changes to the Nano but the error still persists.
When changing the test script to test only write processes we get following error after some time:
[ 488.798065] mmcblk1: error -110 requesting status

And calling umount now leads to:

But the card is still visible at /dev/mmcblk1. I’m not sure but before the patches the card was not listed at /dev when the errors happened.
Is the patch from Jetson Nano SD card enters back to high speed mode instead of uhs mode after soft reboot - #4 by WayneWWW also applicable for Xavier NX?
