Even though I can "sync" from the DDB just fine (and accordind to
the messages on the screen everything was successfully dumped) the
savecore utility can't find any crashdump in the swap...

The kernel shows correct "root on wd0a dumps on wd0b" in dmesg.

# swapctl -lh

/dev/wd0b   128M     128M     4.0K   100%    0

# dmesg
