 I can reproduce the problem on:
  - a physical Dell Latitude D400 laptop (512 MB RAM) running NetBSD-current/i386
  - a physical HP ProLiant DL360 G7 (48 GB RAM) running NetBSD-current/i386
  - the same HP ProLiant DL360 running NetBSD-current/amd64
  - qemu/NVMM running NetBSD-current/i386
  - qemu running NetBSD-current/sparc
 
 I can't reproduce it on:
  - qemu/NVMM running NetBSD-current/amd64
 
 A relatively easy way to reproduce it (not requiring hardware purchases)
 is to install misc/py-anita and emulators/qemu from pkgsrc and run the command
 
   anita install http://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/latest/i386/ 2>&1 | tee console.log
 
 Then look for the string "fvwrite" in console.log.
