That's ok, I have a workaround so it's been on my back burner for a while. >> I can still trigger it on my VM snapshot very easily, so if you have anything >> you think I should test I would be very happy to give it a shot. > > OK, so in the meantime I found a bug in data=journal code which could be > related to your problem.

I have not tried anything more recent; I'm actually a bit reluctant to move away from the Debian squeeze official kernels since I do need the security updates. I took a quick look and I can't find that function in 2.6.32, so I assume it would be a rather nontrivial back-port. It looks like the relevant code used to be in ext4_clear_inode somewhere? Out of curiosity, what would happen in data=journal mode if you unlinked a file which still had buffers pending? That case does not seem to be handled by that commit you mentioned, was it already handled elsewhere? Thanks again!
