>Description:
	The new kernel panics while it tries to mont the root device:

uvm_fault(0xf041f400, 0x2000, 0, 1) -> 5
kernel: page fault trap, code=09
Stopped at _bcopy+0x1a: repe movsl (%wsi),%es:(%edi)

_bcopy(f027bea8) at _bcopy+0x1a
_bread(f04a1600,10,200,f0482a00,f027bf0c) at _bread+0x77
_ffs_mountfs(f04a1600,f04a3a00,f02476c0,24,2e) at _ffs_mountfs+0x197
_mfs_mountroot(ffffffff,f027bfa8,f011e63e,279ffc,279000) at _mfs_mountroot+0xac
_vfs_mountroot(279000,2bb000,fffff000,7ff) at _vfs_mountroot+0x9d
_main(0,0,0,0,0) at _main+0x33e

The same thing happens with a non UVM kernel.
I also get the panic when i boot into singleuser mode.
