It looks like the mount was successful, but that the problem occurred
right after mount. Just as a sanity check does the same thing happen if
you use lock_nolock?

There have been a number of bug fixes since 2.6.20 which went into
Linus' kernel yesterday, so you might want to try the latest upstream
kernel, but I don't recognise this problem as being something we've seen
before,
