        I can reproduce this on _some_ machines using an external USB DVD.
 The problem began sometime between 5.99.13 and 5.99.17.  On "newer" hosts
 the bootstrap bootxx_cd9660 fails, on "older" hosts it works.  This does
 not seem ACPI related, but for me it only fails on hosts with ACPI v2 (it
 does not change if ACPI is disabled or set to v1 mode).  There is the simple
 workaround is to use a 5.x or 5.99.y (y <= 13) disk to start the boot, but
 stop at the boot command prompt - then switch disks (i.e. to -current) and
 then type "boot<CR>".
 
        In my case I'm using the same, not just identical external USB DVD
 hardware, on many different hosts, so the problem is not HW as well as being
 relatively recent in -current AND is likely dependant on some obscure BIOS
 assumption made in the code.
