FBSD 5.3RC1 on Fujitsu Siemenes CELSIUS

[Goran Gajic]

Why kernel was unable to dump to swap partition? I have hoped that I could 
use dump to debug and send report to mailing list as  described in 
developers handbook. I have 4096 MB RAM and 4096MB swap partition. This 
in /etc/rc.conf:
dumpdev="/dev/aacd0s1b"
dumpdir="/var/crash"

and this is my /etc/fstab:

# Device                Mountpoint      FStype  Options         Dump    Pass#
/dev/aacd0s1b           none            swap    sw              0       0
/dev/aacd0s1a           /               ufs     rw              1       1
/dev/aacd0s1g           /home           ufs     rw              2       2
/dev/aacd0s1f           /tmp            ufs     rw              2       2
/dev/aacd0s1d           /usr            ufs     rw              2       2
/dev/aacd0s1e           /var            ufs     rw              2       2
/dev/acd0               /cdrom          cd9660  ro,noauto       0       0

/dev/aacd0s1b is 4MB.
