Subject: Crashkernel memory reservation fails with 2.6.26

Hi,Bernhard/Vivek,
	I was facing the same issue as raised by Sachin sometime back, see below link:

http://lkml.org/lkml/2008/2/4/193

The difference is I am using kernel 2.6.26 while Sachin was using
2.6.24-rc8-mm1.

I saw you were discussing this issue but is there any result?Any
workaround for me?

Thanks
Jason

I was working on x86_64 box, and the message showed during the failure.
