from another system having problems. (i can not get to the console to see what card)

Chip ID is the same on both of those, and on another one I'm talking to that crashes… Mine that run fine are a different chip.

Interesting, my SM board has the same chip ID. My panics come around at 6-8 day intervals with no vpn use, no known factor other than time elapsed.

jimp

LostInIgnorance - one more test for you since you seem to hit it faster than anyone else - can you try switching your OpenVPN instance to TCP instead of UDP and see if it makes any difference? Just curious.

jnorell

Just another "me too" .. panics in devd on the carp backup host. Just got them while adding firewall aliases on the primary (no recent changes to VIP addrs). I'll report if tomorrow's snapshot doesn't stop them.

jimp

vito and others with em failing, can you look at the output of this:

sysctl -a | grep 'dev.em.*fail'

And report any non-zero values. Specifically with dev.em.0.mbuf_alloc_fail and dev.em.0.tx_dma_fail

vito

No non zero's

here is the output
dev.em.0.mbuf_alloc_fail: 0
dev.em.0.cluster_alloc_fail: 0
dev.em.0.tx_dma_fail: 0
dev.em.0.mac_stats.tso_ctx_fail: 0
dev.em.1.mbuf_alloc_fail: 0
dev.em.1.cluster_alloc_fail: 0
dev.em.1.tx_dma_fail: 0
dev.em.1.mac_stats.tso_ctx_fail: 0

Nope, over TCP still did this:

It was worth trying/checking…

Can anyone of you please test with this kernel http://files.pfsense.org/kernel.gz
Just copy it under /boot/kernel/kernel.gz on pfsense and reboot.

LostInIgnorance

@jimp:

For those wanting to debug on ALIX/other embedded devices…
/etc/rc.conf_mount_rw
fetch http://pingle.org/files/kernel_wrap_Dev.gz
tar xzpf kernel_wrap_Dev.gz -C /boot/
And then reboot. It works on my ALIX.

The next snapshot after the one building now should have them in there as well, but not the one building now.

Should I use the above process, just changing the file to http://files.pfsense.org/kernel.gz?

jimp

That kernel is probably for full installs only though, not embedded.

LostInIgnorance

so, not for me? Just for the old dell p4 with the built in em card and everyone else with gig cards.

jimp

Yeah, for the em and not for the Soekris.

eri--

Please try with tomorrows snapshots to see if it is fixed.

ermal,
I installed the kernel and it seems to work.
I copied about 2gb of data with no problems.

may have spoke to soon,
No panic but firewall threw this error and lost all connects.
hard to hard reset the box

pf_test: pf_get_mtag returned null

Hi,

My setup consists of two boxes, both having quad intel nic's ("card=0x10a48086 chip=0x10a48086 rev=0x06" from pciconf -lvb).
Both of the boxes run 2.0-BETA5 (amd64) built on Wed Jan 26 01:53:43 EST 2011.

I have had three different types of errors occuring on these;
1 - Box spontaneously reboots
2 - Fatal trap 12 type error
3 - Box freezes

I only have the OpenOSPFD and Postfix Forwarder packages installed. No VLANs. Current uptime is 50 and 33 minutes. I am expecting one of these boxes to do #1, 2 or 3 above within the next 10 or so minutes. They've been doing that since the upgrade.
(while writing this post, one of them did indeed die by freezing)

Prior to upgrading these two, I had no panics, though I did have other errors, such as connections being reset, which was what prompted me to upgrade.
