Alix 2c3 fatal trap



  • I sucessfuly installed latest embeded image to CF card and booted the board. Everything ok. A soon as I plug in LAN cable on vr1, reboot is triggered.

    Here is what I get:

  • Today I did some more tests and found out that reboots are constant, and not only in case if I attach the LAN cable. Did someone experience the same problems with alix 2C3? Max uptime is around 5 min and then reboot. I have some problems with this board also with 1.2 version and I'm suspecting also fault hardware.

    Can someone confirm that is running 1.3 alpha successful on alix 2C3.

    Thank you,

    Regards,



  • The vr(4) driver was back ported from FreeBSD RELENG_7, guessing that's related to this. We'll check into it.



  • thanks for looking into this. Let me know if you need aditional info/symptoms.



  • Try disabling acpi and report back if it makes any difference.

    I do not know if the ALix2c3 has any MSI features in it but if you can check there might be even a msi disabling test that would be interesting.

  • I'm running the 1.3AA on a 2c3 and it has not rebooted unexpectedly. I have LAN on vr0 and WAN on vr1.
    Connected a laptop to LAN and plugged WAN into my network (dhcp) and browsed the Internet, downloaded files through the box. I then switched the LAN to my private network to play with the AD auth in the usermanager leaving it running all day- no stability issues so far.



  • Disabled ACPI at boot, but no luck, it still reboots. dotdash what kind of CF card are you using?, I will try with different CF card, is pfsense sensitive with different cards? I'm currently using Sandisk extreme II 2Gb card.



  • Use a debugging enabled kernel and post the output of the "bt" command on the debugger prompt.



  • Hi ermal,

    Is there by any chance embeded image with debugging kernel available? I'm not really an expert with this stuff. I found some info here:
    http://devwiki.pfsense.org/ObtainingPanicInfoForDevelopers

    tnx for your help.

    Regards,



  • Check under /kernels there usually you will find different kernels. Not sure if embedded has those too.



  • @dimi3:

    dotdash what kind of CF card are you using?, I will try with different CF card, is pfsense sensitive with different cards? I'm currently using Sandisk extreme II 2Gb card.

    My test box has a 1 GB Kingston. I've got 1.2 production boxes with A-Data, Lexar, Kingston cards. I've never had a problem writing an image to a card.



  • I think he has a hardware problems but better check ;)
