Hello to everyone,
I am having a serious problem not even beeing able to
install FreeBSD 6.1 on this new serever rig.
Here is the hardware configuration and the kernel error message.

I am using original FreeBSD 6.1 i386 images download from ftp.freebsd.org
The hardware setup is:

Arima SW310
AMD Opteron 270 - Dual Core 2.0Ghz
1GB Kingston ECC Registered 400Mhz Memory
No additional hardware installed in the server.

Problem is I can not even get through the boot process of the CD.
After the loader prompt when the OS starts booting it crashes immediately
with the following message.

 Fatal trap 12: page fault while in kernel mode
 fault virtual address   = 0x5a
 fault code              = supervisor read, page not present
 instruction pointer     = 0x20:0xc07b85cb
 stack pointer           = 0x28:0xc1020bd0
 frame pointer           = 0x28:0xc1020c9c
 code segment            = base 0x0, limit 0xfffff, type 0x1b
                         = DPL 0, pres 1, def32 1, gran 1
 processor eflags        = interrupt enabled, resume, IOPL = 0
 current process         = 0 ()
 trap number             = 12
 panic: page fault
 Uptime: 1s

On a second note if i disable ACPI form the loader prompt
the boot process gets further but crashes again with the
following error.

 Fatal trap 9: general protection fault while in kernel mode
 instruction pointer     = 0x70:0x2d10
 stack pointer           = 0x28:0xf70
 frame pointer           = 0x28:0xfc0
 code segment            = base 0xc00f0000, limit 0xffff, type 0x1b
                         = DPL 0, pres 1, def32 0, gran 0
 processor eflags        = interrupt enabled, resume, IOPL = 0
 current process         = 0 (swapper)
 trap number             = 9
 panic: general protection fault
 Uptime: 1s

Any ideas of what might be causing the problem are highly appreciated.
The BIOS version of the MB is up to date.
If there is any other info i can provide you with please ask.
Again this is off of the boot cd so i do not have a crash dump.
I will be trying the amd64 version later tonight - can that be the problem?

Regards:
Ivan Georgiev
