Subject: [BUG] kernel BUG at fs/jbd/checkpoint.c:646!

Hi,

the following bug is present on kernels: 2.6.7-mm6, 2.6.9-rc1-mm1,
2.6.8.1-mm3. If any testing would be needed I can trigger it here in the
matter of hours.

Oops from 2.6.8.1-mm3 attached.

Hope that someone will be able to find a solution for this.

tia,
Krzysztof

You're using data=journal? If so, you'd best turn it off.

I'm not able to reproduce this, as usual. It's on my list of things to ponder.

Yes, that is the case. I hit this bug here every 5 hours or so on 2-3 servers.
Guess I'll turn the data=journal off, for now. If you'd like to get more
info on this I can run modified kernel here if that would help.

Thank you,

Krzysztof.
