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.
