Trying to enable kdump on my remote amd64 wheezy (3.2.0-4) box. Followed all instructions and searched for similar problems, but I can't get kdump-config load to work

Here's my setup:

# kdump-config test
USE_KDUMP:         1
KDUMP_SYSCTL:      kernel.panic_on_oops=1
KDUMP_COREDIR:     /var/crash
crashkernel addr:  0x8000000
kdump kernel addr: relocatable
kdump kernel:
   /boot/vmlinuz-3.2.0-4-amd64
kdump initrd:
  /boot/initrd.img-3.2.0-4-amd64
debug kernel:
  /usr/lib/debug/boot/vmlinux-3.2.0-4-amd64
kexec command to be used:
  /sbin/kexec -p --command-line="root=UUID=51708569-f83b-4f94-97d0-8e8ee5f6567d ro  quiet irqpoll maxcpus=1 nousb" --initrd=/boot/initrd.img-3.2.0-4-amd64 /boot/vmlinuz-3.2.0-4-amd64

and

# cat /proc/iomem
00000000-0000ffff : reserved
00010000-0009ffff : System RAM
000a0000-000fffff : reserved
000f0000-000fffff : System ROM
00100000-1ceffffff : System RAM
01000000-013584a5 : Kernel code
013584a6-01694dff : Kernel data
01729000-01806fff : Kernel bss
08000000-11ffffff : Crash kernel

but

# kdump-config load
Could not find a free area of memory of 91000 bytes...
locate_hole failed
[FAIL] failed to load kdump kernel ... failed!

That was with

crashkernel=160M@128M

I've tried 128M, 128M@16M, 128@32M, 128M@128M Either I get the above error, or the crashkernel doesn't get allocated. I have 8GB of memory.

Anybody have a setting for a similar system that works?
