A 32bit userspace can run with either a 32bit or 64bit kernel. |

A 64bit userspace can NOT run with a 32bit kernel. |

As you currently have a 32bit kernel, I am assuming a 32bit userspace. A 64bit |
| 23 |

I have no experience with Linode. Can't they assist with this? |

Personally, having a forced change like this would make me reconsider the |
