Fatal trap 9: general protection fault while in kernel mode

shadow4dog

I've been trying out 2.4 beta snapshots with my pfSense SG 2440 and about once a day it crashes with this error message. If I revert to 2.3.2 or for that matter 2.3.3 it is rock solid stable.

Does this look more like a hardware issue or an issue with a driver and my hardware?

Grateful for any in-site.

Thanks
Tim

Looks a lot like my issue, you might want to try this:

Add

hw.igb.num_queues=1

to

/boot/loader.conf.local

and reboot.

athurdent: Thank you.

I'd followed your thread with interest. I've also applied those options and rebooted. Hopefully it will stop the instability.

Thanks

Just curious, is the system stable now?

Hi arthurdent,

I've had zero issues since setting hw.igb.num_queues=1.

I guess that issue will have to be fixed by the FreeBSD guys?

Thanks

Thans for the quick response. :)
Lets hope the pfSense developers find something. As you are using official gear I took the liberty to open a ticket.

That sounds sensible. Thank you for your help.

Might be fixed now: https://redmine.pfsense.org/issues/7149

I removed the entry in loader.conf.local and rebooted.

After days of no restarts at all it decided to reboot at 4am this morning. The log says the root user did a restart 15, whatever that means.

It's been running for the last few hours without a panic though and I'll leave it running for a day or so.
