 This seems to be a problem with the acpi_hpet driver.
 Could you please try booting with "hint.acpi_hpet.0.disabled=1" ? This
 way, you should be able to boot with ACPI enabled.
 Escape to the boot loader prompt and type:
 setenv hint.acpi_hpet.0.disabled=1
 
 I believe your hardware must have some problem that's causing a
 divide-by-zero trap. If possible, could you please provide us a
 backtrace from where the panic has originated?
