A truss showed that some kind of shared memory issue going on, but also froze my system hard. After rebooting (kernel was from Nov 26 or 27) fsck could not check my one dirty UFS2 partition. Had to newfs and mtree to recreate /var. No big deal, and I saved an image of it beforehand. After rebooting, there was... NOTHING. GRUB errored out and wouldn't boot. Nothing could see my partitions. After a minimal 4.7-R install (DP2 disklabel whined about offsets and some other STRANGE error messages, so I went with 4.7) on a small fat32 partition, I discovered that the disklabel was empty. Had to edit it by hand... Booted up fine, made a backup, rebooted, and nothing. Not only was there NOTHING, but the disklabel on the new 4.7 install had vanished as well. This time the disklabel had to be recreated with -w -r AND the boot blocks had to be reinstalled. I've seen one post similar to this, but not much else. I think maybe the UFS2 problem had to do with Kirk's recent changes, but the disklabel issue... I'm wary to reboot my machine! What in the hell could be causing this? I'm tempted to point the finger at GEOM, but hate to say anything like that. WNM -- Hi! I'm a .signature virus! Copy me into your ~/.signature to help me spread!
