>Description:
I'm trying to install FreeBSD 4.10 in a new machine which has an Asus           K8V motherboard with an AMD Athlon 64 2800+ CPU and 1GB of PC3200 ECC           memory.  Storage is a pair of Seagate ST-3200822A 200GB UATA-100 disks          in a mirror group on a 3Ware Escalade 7006-2 RAID controller.

Booting either from the FreeBSD Mall CD or floppies I get

   Mounting root from ufs:/dev/md0c                                                             
   /stand/sysinstall running as init on vty0                                   
   panic: page fault

Attempts with 4.9 and 5.2.1 both fail in the same way at approximately
the same location in the boot sequence.

I then temporarily installed an older motherboard and CPU and installed
FreeBSD 4.10-RELEASE.  After switching back to the K8V / Athlon 64 and
booting from the mirror set I again get a panic at approximately the
same location, albeit with more information:

   Mounting root from ufs:/dev/twed0s1a

   giving up on 1 buffers
   Uptime: 14s
   twe0: Cannot delete unit, error = 16

A reset resulted in another failed boot with the only significant
difference being the fault virtual address, 0x45f27e0 the second time.
The other trace information was identical.
