I'm used to having incorrect file data inside files when I have crashes (with WAPBL). I don't like it, but I've seen it. What's new for me here is that there was no crash, not even a reboot, and directories vanished so that even fsck doesn't find them. Well, there was activity on the file system after I noticed them missing, so perhaps the inodes themselves were reused, but what about the contents of the directories? It doesn't make sense to me. > This was with netbsd-5 and then netbsd-6.

So I question my motherboard/cpu and power supply. My bulk builds on this hardware continue to look reasonable, I have ECC RAM (not that this is monitored by NetBSD, but still) and the whole hardware isn't that old (<2 years). Thomas
