Nokia IP110/IP120/IP130 trap 12 crash fix



  • I'm happy to say that I have resolved the issue causing the trap 12 on the Nokia IP110, IP120 and IP130's.  I've run the changes past John Baldwin of the FreeBSD project and the patch will likely be committed to the RELENG_6 & RELENG_7 branches at some point in the future.  It should apply cleanly to 6.1 and 6.2 as well.

    I am attaching the patch to this post.  It should be applied to your FreeBSD sources as follows:

    cd /usr/src/sys/i386/pci
    patch < /path/to/freebsd_nokia_ip1X0.diff

    Assuming both chunks are applied successfully, the resulting kernel will no longer crash on boot.  My next efforts will be trying to find where Nokia hid the MAC addresses for the ethernet controllers.

    Thank you all for your work on this great project!

  • All,

    As a follow-up to this, someone from the m0n0wall forum has found a way to address the invalid MAC address issues:

    http://forum.m0n0.ch/index.php/topic,1471.0.html

    Apparently the drivers are pointing to the eeprom, but the eeprom is blank.  You can use the Intel DOS eeprom update utility to program the MAC addresses into the unit permanently.  I'm going to do some followup to see if there is a way to do this from BSD.

    After this, the only issue left is that the 1X0 devices apparently use a different reboot/reset command.  This may already be available to us by compiling

    options GEODE

    into the kernel.  That is not an option for the standard distro as it changes the way a reset is issued to the CPU.  I'm going to try to sneak some time to see if this resolves the reboot issue this week.
