The commit 722bc6b "x86/mm: Fix the size calcu= lation of mapping tables" which started showing up in 3.5-rc1 causes proble= ms for the crash kernel. You might try this patchset[1] from Jacob Shin and= see if it resolves the problem for you if you are experiencing your proble= m on a 3.5-rc1+ kernel. > = > [1] https://lkml.org/lkml/2012/8/24/474 He has updated the v5 patch set as below: https://lkml.org/lkml/2012/8/29/227 > = > Regards, > Jerry > = >> >> _______________________________________________ >> kexec mailing list >> kexec@lists.infradead.org >> http://lists.infradead.org/mailman/listinfo/kexec > = > _______________________________________________ > kexec mailing list > kexec@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/kexec -- = Thanks Dave _______________________________________________ kexec mailing list kexec@lists.infradead.org http://lists.infradead.org/mailman/listinfo/kexec
