>Description:
Activated ram disk options. Build kernel with root ram disk embedded in netbsd.ram image.
Move netbsd.ram to root directory. Reboot wait till netBSD header come 
up, press space.
On prompt issue command
>How-To-Repeat:
In configuration file activate options
options     MEMORY_DISK_HOOKS
options     MEMORY_DISK_IS_ROOT         
options     MEMORY_DISK_SERVER=1        
options     MEMORY_DISK_ROOT_SIZE=16384  # 8Meg
options     MEMORY_RBFLAGS=0      
 
Build kernel run crunchgen and build  obj exe. Created ramdirectory. Populated directory with needed files.
run
jnetbsd2# makefs -s 8m -t ffs crunch.image ramdirectory
jnetbsd2# mdsetimage netbsd.ram crunch.image
move netbsd.ram to root directory. Reboot wait till netBSD header come 
up, press space.

 I did some preliminary investigation here are results:
 
 Activate -DDEBUG_MEMSIZE in Makefile.boot. Rebuild secondary boot file
 modified diagnostic in loadfile_elf32.c
 
 PROGRESS(("%d fs 0x%x offs 0x%x vadd 0x%x ms 0x%x \n",i, (u_long)phdr[i].p_filesz,(u_long)phdr[i].p_offset, (u_long)phdr[i].p_vaddr, (u_long)phdr[i].p_memsz));
  
   if (lseek(fd, phdr[i].p_offset, SEEK_SET) == -1)  { 
                                 WARN(("lseek text"));
                                 FREE(phdr, sz);
                                 return 1;
                         }
  if (READ(fd, phdr[i].p_vaddr, phdr[i].p_filesz) !=
                             (ssize_t)phdr[i].p_filesz)  {
                         WARN(("\nread text"));
                         FREE(phdr, sz);
                         return 1; 
                   }
 
 
 
 Move boot to /. Reboot repeat above steps and here is printout

 Same error message. It looks that pread() is failing. There is
 enough memory (256M!!!  here is netbsd.ram file data:
