I ran into it with the version fc14 has - Bochs v2.4.5.  I get:

00034041578i[CPU0 ] 0x01fe28e9>> wrmsr  : 0F30
00034041578e[CPU0 ] exception(): 3rd (13) exception with no resolution, shutdown status is 00h, resetting
00034041578i[SYS  ] bx_pc_system_c::Reset(HARDWARE) called
00034041578i[CPU0 ] cpu hardware reset

and then the boot restarts.  The issue goes away if I disable the MTRR
init.
