Hi all, Following up with additional info... I wondered how the stock bootonly ISO from ftp.freebsd.org would behave when booted via PXE since this is how the images will ultimately be delivered. While the error appears different, in that there doesn't seem to be an issue with the USB driver, the media is unable to mount root and fails consistently on each boot, unlike the sporadic behavior when booted via virtual media described in the thread below. I have a few snapshots of the behavior in this scenario: http://www.hostileadmin.com/images/pxe_mountroot_error1.png http://www.hostileadmin.com/images/pxe_mountroot_error2.png Here are the available geom devices: http://www.hostileadmin.com/images/pxe_mountroot_geom_devs.png I've communicated with someone who opened Bug 190939 <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=190939>; ( https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=190939) to which this seems eerily similar. Though I am unable to conclusively identify whether or not it's the same. I also burned the ISO to physical media and booted it. The first attempt to boot was successful with no odd behavior, but the behavior on the 2nd and 3rd attempts differed at the loader prompt with the timer. Output was sent to the screen[1] and it expected either "menu" or "boot" followed by ENTER to boot to the media. Beyond that, the media booted fine. Would this signal a potential issue with the ISO itself?
