Kernel Panic
-
I have a net5501-70, a Pro 1000GT (pci), and a spare pppoe DSL line. Jim, I can set this up with openvpn if you want to test against it. I have no experience with openvpn though, so would need some guidance setting that up.
Also note that my DSL line has pretty poor sync rates right now, and occasional disconnects, which is why it's not in use :/
-
??? JimP, I am a little confused, do you want me to type that in after the crash happens and the db comes up? If not, what would you like from the crash?
Just at a normal command prompt. It will show the chip id of the em card.

I'll keep that in mind, though I was hoping to do it locally since that makes it a lot easier to track down…
-
It might be worth trying without any packages. (the only one I have is OpenVPN client export) to see if it makes a difference.
One thing - for everyone seeing the panic on em(4) devices, the output from
pciconf -lvbFor the em card seen in the crash would be helpful.
Will try later tonight. :)

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.

-
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.
-
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.

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
-
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

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. -
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?
-
That kernel is probably for full installs only though, not embedded.
-
so, not for me? Just for the old dell p4 with the built in em card and everyone else with gig cards.
-
Yeah, for the em and not for the Soekris.
-
Please try with tomorrows snapshots to see if it is fixed.

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