Further digging with Eric's guidance. Modifications to the source:
fs/xfs/Makefile:
EXTRA_CFLAGS += -Ifs/xfs -Ifs/xfs/linux-2.6 -funsigned-char -DDEBUG
fs/xfs/xfs_error.c:
#ifdef DEBUG
int xfs_etrap[XFS_ERROR_NTRAP] = {
EFSCORRUPTED,
0,
};
We've got a trace:
XFS: device md0- bad inode magic/vsn daddr 2064 #0 (magic=0)
