Hi ,
Okay ,I was able to reproduce the problem at my machine.
I have a feeling that the this error can be avoided if you use
CONFIG_LBD in your kernel configuration.
( Device Drivers -> Block Devices - > Support for large block devices )
Please use this option and see whether the problem is still there or not .
Meanwhile , I am trying to figure out a better/complete solution.
