I got a machine which has Intel Pentium Extreme Edition CPU chip
and Intel D955XBK M/B and tried to install NetBSD/amd64 2.1 and
-current.  But cannot boot.  I got warning/error messages:

WARNING: CAN'T ALLOCATE MEMORY SEGMENT 8 (0xcfeec9000/0x20000/014) FROM IOMEM EXTENT MAP !
WARNING: CAN'T ALLOCATE MEMORY SEGMENT 8 (0xcfeee9000/0x20000/014) FROM IOMEM EXTENT MAP !

WARNING: CAN'T ALLOCATE MEMORY SEGMENT 8 (0xcfeff9000/0x20000/014) FROM IOMEM EXTENT MAP !

panic: init386: too many memory segments

Note that NetBSD/i386 2.1 and -current work fine. there are no programs.

Then I tried kernels (both 2.1 and -current) that I manually set
memory size by REALBASEMEM and REALEXTMEM options and it seems
that the system works fine.

Has anyone tried to run NetBSD/amd64 on Pentium Extreme Edition
CPU chips and/or Intel D955XBK M/B?


(hardware)
  CPU : Pentium Extreme Edition (HT, EM64T)
  M/B : Intel D955XBK
  MEM : 4GB
  ...
  
(kernel conf.)
add some options to GENERIC
  options REALBASEMEM=..
  options REALEXTMEM=...
  options MPACPI
  options MULTIPROCCESSOR
  options COM MPLOCK
  ...

(dmesg -- HT is enable (default BIOS setting, but I don't use it))
