On mount. fsck works, even.

As for the trace, there's the following on a simple bt:

#12 0xc0239fe1 in vfs_mount (td=0xc2643720, fstype=0xc0eb3580 "ufs", 
fspath=0xc2764280 "/tmp", fsflags=0,
     fsdata=0x0) at /usr/src/sys/kern/vfs_mount.c:1090
#13 0xc0239748 in mount (td=0x0, uap=0xd1d84d10) at 
/usr/src/sys/kern/vfs_mount.c:846
#14 0xc02eb71e in syscall (frame=
       {tf_fs = 47, tf_es = 47, tf_ds = 47, tf_edi = 134881775, tf_esi = 
-1077937308, tf_ebp = -1077939688, tf_isp = -774353548, tf_ebx = 
-1077939632, tf_edx = 128, tf_ecx = 0, tf_eax = 21, tf_trapno = 12, 
tf_err = 2, tf_eip = 134524695, tf_cs = 31, tf_eflags = 582, tf_esp = 
-1077939844, tf_ss = 47})
     at /usr/src/sys/i386/i386/trap.c:1023
#15 0xc02dae6d in Xint0x80_syscall () at {standard input}:138

Funny that bt full actually stops on that problem.
