Hmmmm.  I think that my 5.0R installation has self destructed.

Background:
* 60GB toshiba disk with two active OS partitions (win2k, freebsd) 
booted with ranish
* Freebsd partition has 4 slices, swap (ca. 2GB), root (250MB), var 
(250MB), usr (ca. 6GB), other msdosfs partitions are occassionally mounted.
* Kernel is 5.0 release p1, updated about 3-4 days ago (don't recall 
exactly but I did notice some updates to ffs.)  Loads ko's for acpi, 
radeon, linux, sound support, and one or two other things I don't recall 
right now.
* Hardware is Asus L3800, (i845-based p4 mobile w/ 1GB RAM).  Has 
otherwise run great with 5.0R (there were acpi problems with RC* 
version, which have disappeared).  The machine is new; it has about 8 
weeks of running time.
* Running configuration is strictly desktop.  Not serving anything, not 
developing anything, not running a db app or similar.
* After a normal shutdown in the evening, the machine rebooted normally 
in the morning.  I logged on to my user account and start X (running 
gnome2).  I checked mail in moz 1.2.1.  I go to open phoenix and nothing 
happens.  I was called away to look at something.  When I return to my 
machine it's in the process of rebooting.  It has hard reset itself for 
some reason and is stumbling through the tail end of the boot up 
sequence and goes into lock, clearly not able to read some thing in /etc 
like ttys (gives a blank shell type prompt, where I have my console set 
to secure.)

Status:
I'm presently running fsck_ffs from a live cd.  It fsck'ed / with some 
complaints about an unreadable sector.  It's now on /var and reporting 
vast, vast numbers of sectors as unreadable, with "UNEXPECTED SOFT 
UPDATE INCONSISTENCY".  I've not visited /usr yet. I hope my disk (with 
less than 800 hours of service) hasn't been somehow physically borked. 
(The windows partition boots and runs seemingly fine.)

Any ideas?  Any guesses about what caused a hard reset (loading 
phoenix)? How to gaurd against this in the future?  (Besides don't run 
5.0R! ;-) ... I'm just hoping to be able to get /usr/home/(user) off, 
I'm assume the installation is utterly trashed.)

/Paul
