kernel hang when machine_restart called from isr

  linux: hardhat linux for powerpc(linux 2.2.14)

  We are calling machine_restart(which call m8xx_gorom) from an isr,
but the kernel hangs after coming to some stage on the restart.

If we call the same machine_restart from a simple ioctl, it works.

  Is there any limitation on the usage of machine_restart?  Does it
assume something which is not true when called from an ISR?
