eri--

Can you please test the new snapshots and see if this is fixed?

FisherKing

Will do. Thanks ermal!

Do you believe the update made it into the current builder run (looks like it started 10:40am EST), or do I need to wait for the build after this?

Michael Sh.

pfSense-Full-Update-2.0-BETA4-20101203-2137.tgz – 5 hours - flight normal. I hope further problems it will not be.

Thanks!

FisherKing

Ok, I've done several tests, need to do a couple more, but here's what I've discovered so far.

It appears that the GUI triggered panic may be cleared up. I'm still able to trigger a panic by calling fetch from the console under specific configuration. It appears to become a problem when CaptivePortal is enabled even though I'm not working from or through the CP interface. I'm not sure which feature in CP is the trigger, so I need to do a little more testing.

Since this thread was more related to the GUI caused kernel panic I suggest we mark this one as solved and I'll start a new thread for the CP related kernel panic once I've narrowed it down.

Ermal - Thanks again for tracking this down!

CryoGenID

Unfortunately, it still doesn't work for me :-(
I just tried the December 5 Snapshot but I still get a panic when trying to update from the GUI…
I will try the most current snapshot tomorrow, just wanted to let you know ;D

Best regards,

Christian

jimp

Trying anything but the most current snapshot would undoubtedly be problematic.

CryoGenID

Update:
Tried the newest snapshot (20.12.2010) but I still get the kernel panic when I try the online update via GUI :-(

Could I do s.th. to help you to figure this problem out?

Thanks and best regards,

Christian

FisherKing

Are you running captive portal?

CryoGenID

PJ2,

thanks for your reply.
Actually yes, I have a CP set up… Do I have to deactivate it?

Best regards,

Christian

FisherKing

turning off CP does the trick for me.

What network drivers are you using? fxp?

cmb

@CryoGenID:

Actually yes, I have a CP set up… Do I have to deactivate it?

That's something to try, it may narrow down the issue considerably.

CryoGenID

@PJ2:
I have these interfaces:
vr0 <- on-Board
ste <- 4-port 100Mbit Card (D-Link)

@cmb:
I have now switched off CP and just clicked on "Auto Update". This time pfSense was able to check if there is a new version without a restart / kernel panic.
Tomorrow will be interesting, as then there'll be an update available.

I will report back, if the update went OK tomorrow, or if I still got a kernel panic :-)

Thanks for your help anyway so far!!

Best regards,

Chris

FisherKing

Thanks Chris -

I've been trying to sort out what it is besides CP that makes the difference. I was hoping that switching NICs would solve the problem for me, but that doesn't seem to be the case. :-/

CryoGenID

Hm… Well if CP really makes the difference, then I am sure that we can sort this, together with the dev, out somehow ;-)

They would be having the same issues if they turn on CP as well, wouldn't they? Or is it indeed coupled with the NIC-type?

I am eager to see what happens tomorrow ;-)

Best regards,

Chris

CryoGenID

Update:
Tried the update today and… it worked ;D

So the problem really seems to be that I get a kernel panic with the update function if there is the CP enabled...

Strange isn't it?

Best regards

Christian

Cino

I was using a ver from the 2nd week of Dec. I would get a kernel panic every time I would start heavy downloading from the internet.. I updated the box to 16th ver and the kernel panics went away. Been updating the box every couple of days after and it seems stable. Only using Snort, no CP.

FisherKing

For a long time I thought I was the only one with this issue. Glad I'm not totally crazy.

Cino

@PJ2:

For a long time I thought I was the only one with this issue. Glad I'm not totally crazy.

I was thinking the same thing until I saw this topic. I had a good reason tho. I swapped my case back to mini-box M300 and started to mess around getting the picolcd to work again. Figured it was that at first but my panic had somthing to do with the nic irqs.

gori

I don't think it's a hardware issue. 2.0-BETA4 (i386) built on Tue Nov 2 14:53:54 EDT 2010 is perfectly stable with Captive Portal active.

Automatic update -> success -> restart -> several minutes running -> kernel panic :-/
disconnect WAN iface cable -> manually update back to the Nov 2 version

I tried these:
pfSense-Full-Update-2.0-BETA4-20101107-0244.tgz
pfSense-Full-Update-2.0-BETA4-20101110-0504.tgz
pfSense-Full-Update-2.0-BETA4-20101115-1340.tgz
and auto-update from Dec 9, Dec 17, Dec 21

all af them crashing in the same way.

Anybody know what has changed with CP between Nov 2 and Nov 7 ?
