hi

i'm having a problem with a bsd disklabel and swap.
my /dev/hda disk look like this

partition 1: fat
partition 2: ext2
partition 3: openbsd

it is a standard bsd disklabel with a as root and b as swap. this means 
that /dev/hda6 should be the swap partition. but "swapon /dev/hda6" 
prints "swapon: /dev/hda6: Invalid argument". it also prints that for 
any other valid partition. if i put this in /etc/fstab, on boot the 
kernel will print "Unable to find swap-space signature" before swapon 
prints the above message. but if i use /dev/hda3 instead, swapon will 
accept it and add a 512Mb swap, which is the correct size. but it 
appears that rather than writing at the start of the swap it starts 
writing at the start of the openbsd partition so my root partition is 
being corrupted. have i screwed or have you guys screwed up?

im running slackware 9 (2.4.20) with a recompiled kernel. my .config is 
attached if you need it.

thanks, daniel
