Is it possible that the elf-image is broken and contains such an address for some reason? afaik this code creates an elf header (or a helper first) per continuous memory chunks it likes to map and export later in /proc/vmcore. Looks like it needs some sanity check there?

Is this address always the same when starting the kdump kernel? Yes, doing a grep (grep ioremap screenlog.krommer) on my serial console log for this machine I get 8 times exactly the same matches: ioremap: invalid physical address db74000000000000 WARNING: at /usr/src/packages/BUILD/kernel-desktop-2.6.37/linux-2.6.37/arch/x86/mm/ioremap.c:83 __ioremap_caller+0x304/0x380() [<ffffffff810324a4>] __ioremap_caller+0x304/0x380
