Hi Lluis,


What kernel are you using? The commit 722bc6b "x86/mm: Fix the size calcula=
tion of mapping tables" which started showing up in 3.5-rc1 causes problems=
 for the crash kernel. You might try this patchset[1] from Jacob Shin and s=
ee if it resolves the problem for you if you are experiencing your problem =
on a 3.5-rc1+ kernel.
