I build an CDROM image with a boot image containing a GENERIC kernel and an "ordinary" FreeBSD-4.4-STABLE installation. After booting the kernel I get the "mountroot> " prompt. On systems having an ATAPI-CDROM mounting the CD as a root filesystem works (giving cd9660:/dev/acd0c as root), but not on SCSI systems (giving cd9660:/dev/cd0c as root). On such systems a kernel panic occurs ("Fatal trap 12: page fault while in kernel mode"). Any ideas? Regards Dirk P. S.
