Created attachment 16462 [details] Crash log and following boot
This was with disk write caches enabled, and raid code that didn't support barriers. I suspect you simply lost the content of all disk write caches.
As never happened again since, I'll just leave it closed but i still think that it is kind of funny for it to loose content that had not been touched for month.
