won't work. But you *may* be able to coerce it into coming up by forcing
the phys_base to whatever it is:
# crash --machdep phys_base=<physical-base-address>
BTW, that's with x86_64 only.
That did the trick. Thanks.
After looking for a line like this in the normal kernel:
Reserving 128MB of memory at 32MB for crashkernel (System RAM: 1024MB)
crash --machdep phys_base=32M -s \
/boot/System.map-2.6.32.27-21-default \
/boot/vmlinux-2.6.32.27-21-default.gz \
/var/lib/xen/dump/sles11_4/2011-0210-1335.40-sles11_4.3.core
