x86: Conditions Under Which Fast Reboot Might Not Work

    The following are possible conditions under which the Fast Reboot feature might not work:

  • GRUB configuration cannot be processed.

  • The driver does not implement the quiesce function.

    If you attempt a fast reboot of a system with an unsupported driver, a message similar to the following is displayed:

    Sep 18 13:19:12 too-cool genunix: WARNING: nvidia has no quiesce()
    reboot: not all drivers have implemented quiesce(9E)

    If the driver for the network interface card (NIC) does not implement the quiesce function, you can attempt to unplumb the interface first, then retry a fast reboot of the system.

  • There is insufficient memory.

    If there is not enough memory on the system, or not enough free memory to load the new kernel and the boot archive, the fast reboot attempt fails with the following messages, then falls back to a regular reboot:

    Fastboot: Couldn't allocate size below PA 1G to do fast reboot
    Fastboot: Couldn't allocate size below PA 64G to do fast reboot
  • The environment is unsupported.

    Fast reboot functionality is not supported in the following environments:

    • An Oracle Solaris release that is running as a paravirtualized (PV) guest domain

    • Non-global zones
