You can find previous messages in the attachments I attached to the report. They are big (500K and 1M), so I compressed and attached them.

> So here probably starts the real oops.
It isn't yet an oops, it's dump_stack() from ext4_destroy_inode() together with hex dump:
static void ext4_destroy_inode(struct inode *inode)
{
if (!list_empty(&(EXT4_I(inode)->i_orphan))) {
ext4_msg(inode->i_sb, KERN_ERR,
"Inode %lu (%p): orphan list check failed!",
inode->i_ino, EXT4_I(inode));
print_hex_dump(KERN_INFO, "", DUMP_PREFIX_ADDRESS, 16, 4,
EXT4_I(inode), sizeof(struct ext4_inode_info),
true);
dump_stack();
}
kmem_cache_free(ext4_inode_cachep, EXT4_I(inode));
}

It was also in the attached file.
