Hi: On a AMD64 X2 box running DragonFly BSD i'm trying to setup test/amd64,
amd64x2# uname -a DragonFly amd64x2 2.4.1-RELEASE DragonFly v2.4.1-RELEASE #7: Wed Sep 30 18:16:27 PDT 2009 r...@pkgbox64.dragonflybsd.org:/usr/obj/usr/src-misc/sys/AMD64_GENERIC amd64 After building 'make scratch' for test/amd64 on the AMD64 X2 box (2GB DDR2, ASUS M2N-MX SE, 320 GB SATA II Seagate, nVidia Gigabit, nVidia SATA controller), the following message was seen WARNING: 64 bit loader installed, if it doesn't work then use 'sysloader' to install the 32 bit one cp /boot/loader /root/qemu//root/boot/loader sync Run the environment with: make QEMUDIR=/root/qemu/ run On running the command, amd64x2# make QEMUDIR=/root/qemu/ run Bus error (core dumped) *** Error code 138 Stop in /usr/src/test/amd64. amd64x2# On attempting to debug, amd64x2# gdb `qemu-system-x86_64 -curses -hda root.img -m 128 -no-fd-bootchk` qemu-system-x86_.core We need a terminal output gdb 6.7.1 This GDB was configured as "amd64-dragonfly"...
