>Description:
I'm download iso-image from this address:

http://ftp.netbsd.org/pub/NetBSD/NetBSD-7.0_RC1/iso/NetBSD-7.0_RC1-i386.iso

then write on CD-RW and boot from it on old Toshiba Tecra 550CDT (Pentium MMX 266MHz, 96M RAM).

There is fragment of kernel messages:

(start of fragment)

 uvm_fault(0xc0ff0d00, 0, 1) -> 0xe
 fatal page fault in supervisor mode
 trap type 6 code 0 eip c0904718 cs 8 eflags 10286 cr2 1c ilevel 8 esp 1
 curlwp 0xc0fa69e0 pid 0 lid 1 lowest kstack 0xc119e2c0
 kernel: supervisor trap page fault, code=0
 Stopped in pid 0.1 (system) at netbsd:cfparent_match+0x14: movl 1c (%esi)
 ,%eax
 db{0}>

(end of fragment, end of boot)

On NetBSD v. 6.x.x on this Toshiba Tecra 550CDT boot process work well.
