Thanks for trying this out. As Vivek mentioned can you please try with bulding
second or dump capture kernel with CONFIG_SMP=N and _without_ maxcpus= option.
Basically the second kernel's job is just to save the dump and it doesnot need
to be a SMP kernel. There are some issues with booting SMP kernel as dump
capture kernel.
Also, it would be great help if you can also send us some hardware details
about the system you are trying, like lspci, /proc/cpuinfo and which kernel
you tried. I am maintaining a webpage to consolidate the test reports of kexec/kdump
at
http://lse.sourceforge.net/kdump/kdump-test.html
Thanks
