Hi. When booting into Jolla recovery on my Xperia XA2 and performing a file system check I get these I/O errors:

  /dev/mmcblk0rpmb: read failed after 0 of 4096 at 0: Input/output error

I'm able to boot into Sailfish and use it without any issues. I tried reinstalling Android and Sailfish again but ended up with the same errors. I'm currently on SailfishOS 3.3.0.16.

After reaching out to Jolla Care they confirmed that they get the same output on a perfectly working XA2 with SailfishOS. I thereby assume this is a bug in the filesystem layout.

Is the system check allowed to read the Read Protected Memory Block? Would that be paradox? I mean, I would absolutely expect the outcome above, otherwise encryption and other anti-manipulation measures would be pointless, or am I wrong?
