Reboot not working with the newly built upstream custom kernel

Hello,

I am trying to build the upstream kernel like linux-linaro-3.0,
linux(linus), linux-next, linux-arm-soc for next builds with omap2plus
defconfig,
Create a kernel debian package and use this debian package to verify the
build. The builds are enabled with ext3 file system.

The scripts that is used to build the kernel for example is
http://bazaar.launchpad.net/~linaro-infrastructure/linaro-ci/lci-build-tools/view/head:/jenkins_kernel_build_inst
.
The builddeb used contains modifications submitted to work for cross
compilation and the changes are available at
http://permalink.gmane.org/gmane.linux.linaro.devel/7443.
Other than that there is no hand made changes to any files.

An example hwpack that I created using the linaro-hwpack-replace can be
downloaded from
http://ci.linaro.org/kernel_hwpack/panda/hwpack_linaro-panda_20110927-0741_armel_supported.tar.gz
.
This consists of the kernel debian package built from linux-linaro-3.0 with
omap2 defconfig  to work on a panda board.

[PS: linaro-hwpack-replace which is part of the linaro-image-tools is a tool
that replaces the old kernel debian package in a given hwpack with the
supplied kernel debian package ]

I see that the kernel builds successfully, and the hwpack containing this
newly built kernel debian package boots fine on the boards, but it fails to
execute the reboot command and it hangs
with the following message:

#################################################################

The board needs to be hard reset to boot back to the system.
Has anyone seen this issue before, or do you suspect some problem with the
kernel I built ??
I would be very thankful if someone can help me triage the problem.

Thanks and Regards,
Deepti.
