Americo, I downloaded the source for kexec-tools 1:2.0.2-1ubuntu3 and rebuilt it with -DDEBUG and installed. Below are the results using the 2.6.38-8-server Ubuntu kernel as base and crashkernel. Note that the crashkernel size has been increased to 479M. While I have the list's attention, I would like to mention another problem in this area. The 2.6.38-8-server kernel cannot create a crashkernel area greater than 479M in size (e.g. crashkernel=480M). If the crashkernel is relocated (e.g. crashkernel=480M at 8G), then the kernel will create the area but kexec (1:2.0.1-1ubuntu3) fails while attempting to load crashkernel into the reserved area. This is a fatal problem since the 2.6.38-8-server kernel running as crashkernel requires more than 479M of crashkernel area to successfully take a dump on our systems. I will be happy to provide additional information about this one as well.
