panic with firewire hd & dump wrongly says swap is too small

Hi,

Today I plugged in my firewire HD into my amd64-CURRENT system.

# uname -a
FreeBSD mchammer.arved.de 5.2-CURRENT FreeBSD 5.2-CURRENT #11: Tue Apr  6 22:03:32 CEST 2004     root_at_mchammer.arved.de:/usr/obj/usr/src/sys/MCHAMMER  amd64

The following happend:

Unfortunately I couldn't produce a dump, because doadump was telling me

db> call doadump
Dumping 1023 MB

Dump failed. Partition too small.
0x23

Although my swappartition is large enough:
# swapinfo
Device          1K-blocks     Used    Avail Capacity
/dev/ad4s1b       2070336        0  2070336     0%

Any idea, hints?
