While in a x86 box, it is 931131392 which looks sane. [root@test8 ~]# ll /proc/kcore -r-------- 1 root root 281474974617600 Jun 5 11:15 /proc/kcore [root@ocfs2-test9 ~]$ ll /proc/kcore -r-------- 1 root root 931131392 Jun 5 11:58 /proc/kcore I just noticed this when kexec fails in "Can't find kernel text map area from kcore". Is there something wrong?
