[520815.675967] Kernel panic - not syncing: Fatal exception in interrupt
[520815.675967] Rebooting in 12 seconds..
[520815.675967] ACPI MEMORY or I/O RESET_REG.


The first is a UTM425r5 while the second is a UTM320r5.  The second only has 2 Application Control rules, an allow for Facebook for select users and a block for Facebook.  The first has numerous Application Control rules including a block for Facebook.

Since changing to more traditional approach of Firewall and Web Filter rules for Facebook, neither have crashed (though the elapsed time of only a few days is far too short to be conclusive).  I have a case that's been elevated to Sophos development and have asked their thoughts on using Firewall and Web Filter rules prior to my change to those but seen no response.

At netfilter/iptables development I see a similar panic and now have a suspicion on a Mantis ID number but have not seen a more recent post with a patch.

Has anyone seen a panic like this?  Does my assessment sound fair?

  • Thanks for the confirmation.  Due to the timing of that netfilter-devel email, I doubt that it was my case initially but I've had a case open since 2014-03-27 and after updating in an effort to resolve that issue, started seeing the panic (digging for first occurrence).  Fortunately, I haven't seen any panics from any other appliance on 9.109+ yet.

    Edit: The first spontaneous reboot appears to be 2014-03-27 on 9.109 (per log search).
