Well, technically, that's Jens.

However, what's the actual bug here ... as in what's going on?

The kernel trace implies that some user land process tried to read block
0 and got told it's not readable, giving an I/O error.

MMC says this usually happens when you try to read a sector with the
wrong mode ... what is the program doing the read?
