Kernel Panic
-
Sorry to be so dense… does this mean that the update that I'm performing right now will have the discussed fixes?
-
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.
-
tested one more time and it crashed again. :(
-
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.
-
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?
-
In theory it should be about the same, but in practice that isn't always the case.
-
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?
-
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)
-
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. -

I will get back when i hav emore info on this new issue.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?

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

I'm currently on "Fri Jan 28 00:53:50 EST 2011".Oh, and my backup just became the master spontaneously again.
Excellent work btw. Much appreciated!
-
yes, wait for the next one. It was just restarted to pick up the patches he pushed.
-
@vito please type a bt at that prompt next time.

it is a hard lock…can't type anything in.
On reboot, still do not see the crash files that jimp added.
