[Crash-utility] crash: invalid structure member offset

[Koornstra, Reinoud]

Hi Everyone,

I am trying to read a core file into crash, but I've got bad luck as you can see below.
Is core file corrupt? It is a vmcore file from a 32 bits kernel that was compiled with PAE, could that have corrupted things?
Any hints here?
Thanks,

Reinoud.

$ crash System.map-2.6.27 ./vmlinux-2.6.27 ./vmcore
