Kernel Panic

eri-- · Jan 27, 2011, 8:10 PM

Yeah just download the file after this post i updated it again.

eri-- · Jan 27, 2011, 8:43 PM

FYI i just committed some patches to pfSense repo which should fix the hangs and the panics.
All those on non full installs of i386 grab the next snapshot and test when it comes out.

Since the snapshot builder won't be done with its current run for a while yet, I ran off an i386 full update on my builder and uploaded it here:
http://cvs.pfsense.org/~jimp/pfSense-Full-Update-2.0-BETA4-i386-20110127-1627.tgz

If someone wants to give that a shot, have at it. The amd64 builder doesn't take quite as long, it should be up in a couple hours, the nanobsd builds probably won't be up until after midnight.

Jimp,
does this have the kernel that had to be downloaded included or do we need to still do the update then download the kernel from ermal's post?
Thanks!

Ermal checked the patches into the repo so this should be equivalent to that, or better.

Sorry to be so dense… does this mean that the update that I'm performing right now will have the discussed fixes?

jimp · Jan 28, 2011, 12:38 AM

Not if you're doing an auto update. The snapshots are still building, probably won't be done for a couple hours.

I posted a URL earlier to a build I made for i386 full installs that should have the fixes, though it didn't fix my problem (FTP still has issues…)

~~I just installed your build from the link jimp…testing now...~~

Update: with the snap from your link the system did panic.

jimp, is the text dump in this build? i just went to look for it and do not see the file.

vito · Jan 28, 2011, 1:05 AM

tested one more time and it crashed again. :(

jimp · Jan 28, 2011, 1:20 AM

Textdumps should be on in those builds… see my other post: http://forum.pfsense.org/index.php/topic,32711.0.html

I guess just wait and try the 'real' snapshot when it uploads later tonight.

vito · Jan 28, 2011, 1:29 AM

yep, i saw the post and checked /var/crash
nothing in the folder.

will the build on the snap server be different then the one you posted?

jimp · Jan 28, 2011, 1:32 AM

In theory it should be about the same, but in practice that isn't always the case.

clahti · Jan 28, 2011, 1:34 AM

quick question, I am in the freeze/hang camp. I don't get a kernel panic on the console, so when I update to the next snapshot should I expect a dump in /var/crash when the system hangs?

jimp · Jan 28, 2011, 1:45 AM

No - the hangs you can't get out of except by a power cycle. There is no crash dump from a hang, only from a panic. (This thread is really for the panics… the hangs have a separate thread)

clahti · Jan 28, 2011, 1:55 AM

ya that's what I thought, thanks.

Today one of the fw's (running "2.0-BETA5 (amd64) built on Thu Jan 27 19:46:43 EST 2011") managed to output something in /var/crash/ before it died.

See attached files.

That seems like another panic related to carp and your link going up down.
So seems like progress, at least to those who do not have intensive carp clusters but just hangs.
I will get back when i hav emore info on this new issue.

@ermal:

I guess that would explain why the backup spontaneously becomes the master every now and then?
I get this on the backup:
BACKUP -> MASTER (preempting a slower master)

and this on the master:
MASTER -> BACKUP (more frequent advertisement received)

Adjusting advskew probably won't help here, I guess?

eri-- · Jan 28, 2011, 2:27 PM

I have pushed some patches that should solve even the carp panic Slaygon.

So newest snapshots should have the fix for you.
I would skip the next one coming and get the other one.

vito · Jan 28, 2011, 2:52 PM

just tried snap
2.0-BETA5 (i386)
built on Fri Jan 28 05:30:15 EST 2011

and it crashed. :)

The only one i had any luck with is the first kernel that was posted.

Just so i am clear… the snaps have the correct kernel or do i still need to download from the separate link?
