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?

    Try disabling 'hostres'  as suggested here:
    If it works put the tunable in /boot/loader.config.local

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


  • Thank you for your help with resolving my USB mountroot error. 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

  • Successful in booting 2.2 from another usb stick without any fuss. Must have been some compatibility issue with the first usb stick and 2.2 so I will use it for 2.1
