:Hello all,
:
:I recently purchased an Intel D945GCLF Mini-ITX motherboard with Intel
:Atom. I got DragonFly up and running on it out of the box except for
:the network, card which required a minor patch.
:
:It even runs X with KDE 4.1.1 with DRI support and sound. pciconf -v
:currently shows only 1 undetected device, and that it seems is a SMBus
:device (which I guess I can enable with "device smbus"):

    Well, that's pretty cool!

:Apart from that, the network card is a Realtek 8102EL, which is not
:detected with a vanilla kernel. I modified the "re" driver source code
:to include the hardware revision of the 8102EL and disable the
:hardware checksum features of the card (they don't work probably
:because it has changed), see patch below.

    Your changes have been committed!  Thanks!

:There's only few minor issues with the network card still present;
:when the kernel boots I occasionally get the following error message
:and the kernel crashes just before it should start booting into
:userspace:

:
:Setting the "debug.acpi.disabled" variable to "bus timer" seems to
:completely cure the problem, however I'm still wondering if it is
:something wrong with the patch or if it is an isolated ACPI issue.
:
:So my question is, is the patch correct or I just encountered an ACPI issue?
:
:Regards,
:Mitja Horvat

    If it works with ACPI disabled then that is what you should
    go with.  There certainly can be some BIOS issues, possibly with
    plug-n-play or ACPI.  Go with what is reliable.
