FreeBSD t5048.genken.com 6.3-RELEASE FreeBSD 6.3-RELEASE #0: Wed Jan 16 04:45:45 UTC 2008 root@dessler.cse.buffalo.edu:/usr/obj/usr/src/sys/SMP i386
>Description:
Running 6.3 release from .iso disk image. No modifications to kernel. At 512 M of DDR2 memory, everything runs great.
..
ohci0: <ATI SB400 USB Controller> irq 19 at device 19.0 on pci0
ohci0: [GIANT-LOCKED]
usb0: OHCI version 1.0, legacy support
usb0: <ATI SB400 USB Controller> on ohci0
usb0: USB revision 1.0
..
Then I add 1 G of DDR2 memory so I have a total of 1.5 G of memory. XP runs great (dual boot with each OS on its own disk). I even swapped the location of the memory cards, i.e. 1G in one slot, and 512M in the other slot. XP still ran fine. When I try FreeBSD, swapped or not, it hangs on boot up.
..
ohci0: <ATI SB400 USB Controller> irq 19 at device 19.0 on pci0
ohci0: [GIANT-LOCKED]
usb0: OHCI version 0.0
usb0: unsupported OHCI revision
ohci0: USB init failed
device_attach: ohci0 attach returned 5
..the machine is hung at this point...
>How-To-Repeat:
Leave in the 1G chip.
Also tried booting from the 6.2 release .iso image as well as booting off the 6.3 release .iso image -- install kernel hung both times with the 1G chip added for a total of 1.5 G.
>Fix:
Remove the 1G chip.
