photo of terminal with divide error: 0000 kernel panic

I left this Arch Linux NAS running for about 20 days and all of a sudden it died; I checked the terminal window today and found kernel panic in attachment. By searching online I found a bug report for same kernel panic that is mistakenly attributed to VirtualBox (https://www.virtualbox.org/ticket/12070), however I am running on bare metal here (Intel i3-4340).

Never seen this before and I am afraid it will be a bit difficult to trigger it again; I wanted to contribute with this bug report as I thought it is a rare kernel panic.

Sorry for the bad quality of the screenshot, it's the best I could do as I don't normally connect a serial tty to this box. A section of photo (related to modules) was removed because of the flash flare. If it can be of help, these are the modules currently loaded (and there's no reason to suspect they would be any different at time of incident):

Comment 1 Dirk Brandewie 2014-11-06 15:18:50 UTC
is this issue still occurring?
Comment 2 Kristen 2014-11-18 18:29:15 UTC
This is an old bug that has already been fixed.  Please reopen if the problem is still around in the current kernel.
Comment 3 Daniel 2014-11-19 08:30:46 UTC
@Dirk sorry for the late reply, I am not experiencing this issue anymore but I do run a more recent kernel version of another distro now.

@Kristen thanks for the information, closing
