Yes. Deadlocks that weren't properly fixed until 2.6.18 (partially
fixed in 2.6.17) and an accounting problem in the transaction code
that leads to the shutdown you are seeing. The accounting problem is
fixed by this commit:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=45c34141126a89da07197d5b89c04c6847f1171a

which I think went into 2.6.22.

Luckily, neither of these problems result in corruption.

Yes - a problem with readdir. The fix is currently in the stable
queue (i.e for 2.6.24.3):

http://git.kernel.org/?p=linux/kernel/git/stable/stable-queue.git;a=commit;h=ee864b866419890b019352412c7bc9634d96f61b

So we are just waiting for Greg to release 2.6.24.3 now.

Cheers,

Dave.
