[U-Boot-Users] Unable to boot linux 2.6.25 with U-Boot 1.1.4

Hello everyone. I have got a modified u-boot source which boots vanilla 2.6.22 kernel, but is unable to boot vanilla 2.6.25.

The message I get is this : Uncompressing Linux.......................................................................................... done, booting the kernel.

Nothing shows up after this. The modified U-Boot version is "U-Boot 1.1.4".

Could somebody help. Thanks in advance Rohit
