Problems with SD card

Hello. I recently purchased an H5555, and everything works well, except
for my 256MB Sandisk SD card. I mount it, and then whenever I try to do
something like "ls" inside of the directory, it hangs. I get this
message in dmesg two times: "ignoring mmc irq with null request". I'm
aware that this is a common problem, but I'm wondering, is there a way
around it? I really need that extra storage, because without it I don't
have enough to store anything.
