Actually that particular issue was addressed in crash version 5.0.2
that was just released this week:
- Fix for initialization-time failure on 2.6.34 and later kernels that
were configured with CONFIG_NO_BOOTMEM. Without the patch, the crash
session fails with the error message "crash: invalid structure member
However, if 2.6.34-rc2-mm1 has this patch (and I presume that is since it's
in 2.6.34-rc3), then you're temporarily out of luck:

percpu: remove per_cpu__ prefix.
Now that the return from alloc_percpu is compatible with the address
of per-cpu vars, it makes sense to hand around the address of per-cpu
variables. To make this sane, we remove the per_cpu__ prefix we used
created to stop people accidentally using these vars directly.
Now we have sparse, we can use that (next patch).
tj: * Updated to convert stuff which were missed by or added after the
* Kill per_cpu_var() macro.
