fails to mount root

[Pierre Abbat]

My UPS glitched and rebooted the computers. The DF box kernel-panicked like 
this:

lockmgr
vx_unlock
vnode_terminate
_sysref_put
vrele
vput
hammer_recover_stage2
hammer_vfs_mount
vfs_mount
vfs_mountroot_try(c06e220a,0,c[6e21f8,c8,0) at vfs_mountroot_try+0x242 
0xc03df6de
vfs_mountroot(0,e68c00,e68c00,e79000,e79000) at vfs_mountroot+0x8c 0xc03dfbb8
mi_startup(e68000,0,0,0,0) at mi_startup+0x89 0xc0358af0
begin() at begin+0x42 0xc0164b3b
Debugger: panic()

CPU0 stopping CPUs: 0x00000002

I tried safe mode, single-user mode, and an old kernel, all with the same 
result. Now what do I do?
