While running the fsx tests on 2.6.31-rc8 kernel, the above mentioned occurred.

Steps for running fsx test:
1. Create an ext4 partition with blocksize 1024 and mount it with 
"-o errors=panic,data=journal" options
2. Install the autotest framework
3. Run fsx test attached to this bug
4. Check the dmesg.

You can see several messages like the one below:

kernel: JBD: Spotted dirty metadata buffer (dev = sdb5,
blocknr = 41444). There's a risk of filesystem corruption in case of system
crash.

Thanks
Muni

Guys, are you still able to reproduce the problem with 2.6.32 kernel?
