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?
