  https://www.illumos.org/issues/8508
    Mounting a zpool on a 32-bit system triggers a panic in spa_history_log_version
    () due to a type format mismatch for ZPL_VERSION. ZPL_VERSION is a unsigned
    long long, but the format expects an integer. On 64-bit platforms this may not
    be an issue due to word size and alignment. On 32-bit platforms a word size is
    half that of a long long, causing the second word of the long long to be seen
    as the string pointer for utsname.nodename.
