<![CDATA[Resolve USB mountroot error]]>I downloaded pfSense-2.2-RELEASE-4g-amd64-nanobsd-vga.img with the intention of running pfsense 2.2 from usb. Writing the image and default booting nanobsd 2.2 on my atom d510 results in a mountroot error 19.

Troubleshoot guide suggests to escape to loader prompt and enter the following but to no avail. Any ideas?

set kern.cam.boot_delay="10000"
boot

Must have been some compatibility issue with the first usb stick and 2.2 so I will use it for 2.1

I will need another usb key to try 2.2 image with the suggested

set debug.acpi.disabled ="hostres"

Same setup boots with 2.1 image. Snippet from 2.1 log

http://wiki.pcbsd.org/index.php/Talk:Installation_Troubleshooting
If it works put the tunable in /boot/loader.config.local

Does it boot a 2.1.5 image boot in the same setup?
