Kernel Panic
-
I did notice this on the console after having to uninstall and reinstall HAVP.

Don't worry about LORs, they're mostly harmless.

Did notice this from both panics though.
Panic from old P4 computer:
Kernel page fault with the following non-sleepable locks held: exclusive sleep mutex em0 (EM TX Lock) r = 0 (0xc2f52580) locked @ /usr/pfSensesrc/src/sys/dev/e1000/if_lem.c:1350Panic from Soekris board:
Kernel page fault with the following non-sleepable locks held: exclusive sleep mutex vr1 (network driver) r = 0 (0xc3640aec) locked @ /usr/pfSensesrc/src/sys/dev/vr/if_vr.c:1675Is it just coincidence?

Hi, I've reinstalled the secondary machine, it's now running 2.0-BETA5 (amd64) built on Mon Jan 17 22:14:04 EST 2011 (the primary has 2.0-BETA5 (amd64) built on Fri Jan 21 23:51:34 EST 2011).
I disabled the sync, created all the remaining carp vips on the primary (I've 12 of them right now), and re-enabled the sync. The secondary didn't crash.
What shall I do now? I'm a bit scared of upgrading it :-) thanks
-
Just wait for build late build from today and it should be safe to upgrade.
-
ok, and which kernel should I be running? SMP or devel? thanks
-
as of snap
2.0-BETA5 (i386)
built on Mon Jan 24 18:48:13 EST 2011fix did not work.
Maybe fix was not in this build?

It should have been.
So it still crashed the exact same way, with the same panic in the same place?

Hard to say for sure.
I just setup my ALIX and opened a ton of browser tabs and pushed a bunch of traffic through it and I managed to crash Chrome but not the router… I wish I could reproduce this.

Here is the new screen shoot of the panic.
Same symptoms, only when using openvpn
-
The key is only when you connect to OpenVPN and then after successful connection, open a browser and the page should time out and you should get disconnected from the OpenVPN connection.
-
I had ~10 browser tabs open to all kinds of sites, streaming a youtube video, and was copying a file over SMB, all over OpenVPN from a client on the WAN side of my ALIX.
Perhaps it's a bug specific to the vr chip in the Soekris.
-
If it is a specific issue to the vr chip, then why am I getting the same type of panic with the em (as I had posted above)?
-
Bad luck? :-)
The em chips hit by this are specific older chips that fall under the "legacy em" ("lem") portion of the driver code.
-
LOL, seems to be me only that has the bad hardware then.
EDIT: Did you try it with squid havp, etc. loaded on it?

Note the case for me,
Once connected i would start up outlook to sync to exchange and openvpn would crash
Same goes with doing a file/folder copy from host network to openvpn client. -

-

I haven't tried it with squid, I'll load that on next. Do you have the OpenVPN server assigned as an interface and squid listening there? Otherwise, squid wouldn't be doing anything to the traffic coming from OpenVPN
-
No I am not having squid listen to anything but the 3 different vr networks. I am just wondering if the setup may have something to do with it. Doesn't hurt to recreate it completely.
-
fair enough. I'll give it a go.
