>Description:
If I use gbde for swap device, it does something bad with filesystem, because after second reboot my computer stops after bios rutines, on screen is F1 - FreeBSD, but if I press F1 or enter it on beeps and does nothing

I tried it on two computers (5.3-BETA3 and 5.3-BETA7), both give the same result
>How-To-Repeat:
Easy, you can add gbde_swap_enable="YES" to /etc/rc.conf and change swap line if fstab from: 
/dev/ad0s1b             none            swap    sw              0       0
to:
/dev/ad0s1b.bde         none            swap    sw              0       0

then reboot to set up swap, and then reboot ones more to set what happend

OR

manually, init /dev/ad0s1b, attach /dev/ad0s1b and so on, the result is same
>Fix:
Do not use gbde for swap?
