   Yes, memtest86 didn't show anything weird.

   I have background_fsck="NO" in rc.conf and I checked the whole disk
several times.
   Something I forgot to mention earlier: the crash is easier to
reproduce when running rtorrent. The machine did crash without running

If it's there, and you can see it, it's real.
If it's not there, and you can see it, it's virtual.
If it's there, and you can't see it, it's transparent.
If it's not there, and you can't see it, you erased it.
