Can you try reverting this change: Author: jhb Date: Thu Apr 28 17:44:24 2011 New Revision: 221177 URL: http://svn.freebsd.org/changeset/base/221177 Log: Due to space constraints, the UFS boot2 and boot1 use an evil hack where boot2 calls back into boot1 to perform disk reads. The ZFS MBR boot blocks do not have the same space constraints, so remove this hack for ZFS. While here, remove commented out code to support C/H/S addressing from zfsldr. The ZFS and GPT bootstraps always just use EDD LBA addressing. MFC after: 2 weeks Modified: head/sys/boot/i386/boot2/Makefile head/sys/boot/i386/common/drv.c head/sys/boot/i386/zfsboot/Makefile head/sys/boot/i386/zfsboot/zfsldr.S -- John Baldwin
