Major filesystem problems after crash on 7.0-BETA3

[Doug Poland]

Hello,

This morning my 7.0-BETA3 i386 system (Compaq nx7400) reset shortly
after starting X11.  I didn't think much of it and went to get a cup
of coffee while the background fsck took care of the file systems.

Unforunately, something's still broke.  At first, when I tried to
access the /var or /tmp filesystems, I received panics similar to:

mode = 0100644, inum = 31127, fs = /tmp
panic: ffs_valloc: dup alloc
cpuid = 0
Uptime: 9s
Physical memory: 3435 MB
Dumping 101 MB:Aborting dump due to I/O error.
status == 0x4, scsi status == 0x0

** DUMP FAILED (ERROR 5) **
Automatic reboot in 15 seconds - press a key on the console to abort


After doing some googling, it looked like my filesystems weren't
really clean after several manual runs of fsck.  So I disabled
softupdates on /var and /tmp and ran fsck on those file systems again.
 After mounting them rw, I attempted to hit the filesystem again, this
time getting a panic:

panic: ffs_clusteralloc: map mismatch
cpuid = 1
Uptime: 6m40s
Physical memory: 3435 MB
Dumping 149 MB:Aborting dump due to I/O error.
status == 0x4, scsi status == 0x0

** DUMP FAILED (ERROR 5) **
Automatic reboot in 15 seconds - press a key on the console to abort

Is there a way to identify and fix these errors?  I'm thinking a newfs
of both /var and /tmp is in order.  I don't really care about /tmp,
and I've backed up /var using dump(8).  My concern is if I restore
/var on top of a newfs'd filesystem, I'll restore my broken files and
have the same problem again.

Please advise...
