panics and crash dumps

I'm having problems getting a crash dump on my panics.
A bog standard crash dump on panic to swap hangs during the dump. Kris
recommended trying minidump or DDB. With minidump enabled, it hangs,
doesn't even try to dump on panic.
So on to try DDB, have these lines in my kernel:
makeoptions DEBUG=-g
options KDB
options DDB
and now this kernel, when it boots, it doesn't see all of the sata drives.
I have 2 sata controllers, one on the motherboard, the other a pci card (a
supermicro controller). The only difference in the kernel conf files are
the latter 2 options lines above being added. I did not see any errors
while compiling this kernel. The same kernel modules are in kernel.old as
in kernel, however, these are the ones that differ:
[#1022] diff -r kernel kernel.ddb.broken
Files kernel/bktr.ko and kernel.ddb.broken/bktr.ko differ
Files kernel/geom_eli.ko and kernel.ddb.broken/geom_eli.ko differ
Files kernel/hptrr.ko and kernel.ddb.broken/hptrr.ko differ
Files kernel/ibcs2.ko and kernel.ddb.broken/ibcs2.ko differ
Files kernel/if_ed.ko and kernel.ddb.broken/if_ed.ko differ
Files kernel/if_oltr.ko and kernel.ddb.broken/if_oltr.ko differ
Files kernel/kernel and kernel.ddb.broken/kernel differ
Files kernel/linker.hints and kernel.ddb.broken/linker.hints differ
Files kernel/logo_saver.ko and kernel.ddb.broken/logo_saver.ko differ
Files kernel/mem.ko and kernel.ddb.broken/mem.ko differ
Files kernel/rr232x.ko and kernel.ddb.broken/rr232x.ko differ
Files kernel/udf.ko and kernel.ddb.broken/udf.ko differ
When my DDB kernel boots, not only does it not see the sata drives, upon a
quick reboot, it panics and does not throw me into the debugger. And then,
to my surprise, it does a crash dump into swap. But when the machine
reboots, it can't read it! I get:
Checking for core dump on /dev/ad1s1b...
savecore: error reading last dump header at offset 10005032448 in
/dev/ad1s1b: Input/output error
savecore: no dumps found
Jul 21 04:45:17 charm savecore: error reading last dump header at offset
10005032448 in /dev/ad1s1b: Input/output error
Here is the screen output of the crash of the kernel with DDB which did not
recognize the second sata controller:
