This should more be an informal bug report for others runnign into the issue, to make their life easier.
The XA2 Kernel (4.4) will crash with f2fs filesystems from the latest kernel releases ( at least 6.1, but last time I formatted the sdcard was with 5.2 or so). Formatting on the device itself will solve the issue of your crashes. Appending the kernel log from the crash.
