freebsd-questions:

I did another install, set the protective MBR boot flag on the USB 
drives using Linux fdisk, booted the machine, entered the encryption 
passphrase, and it crashes:

	Enter passphrase for da0p4: GEOM_MIRROR: Force device swap start due to 
timeout.
	
	GEOM_ELI: Device da0p4.eli created
	GEOM_ELI: Encryption: AES-XTS 256
	GEOM_ELI:     Crypto: software

Any ideas?


TIA,
