Filesystem corruption, read-only filesystem, and eMMC problems

I have numerous 64G UP Squared boards that are currently running Ubuntu 18.04 with the UP kernel version 5.4.0 and the most recent (v6.1) UP bios. I have been consistently getting a corrupted filesystem that sometimes ends up read-only and often displays mmc issues in the kern.log file as shown below. This is happening in the middle of operation with no power loss issues.

kernel: [ 5710.200889] mmc0: mmc_select_hs400 failed, error -84
kernel: [ 5710.201463] mmc0: mmc_hs400_to_hs200 failed, error -110
mmcblk0: error -110 sending stop command, original cmd response 0x0, card status 0x400900
mmcblk0: error -110 transferring data, sector 22099648, nr 8, cmd response 0x0, card status 0x0

I have previously used the older 128G UP Squared boards for the same purposes as I am using them now and never ran into this issue.

Any ideas on what could be causing this across multiple boards?

    Hi @nattip ,

    Sorry to read this, can you tell how many units have this issue? Can you also send the output of uname -a and dmesglog to my email. (find on my profile)
