Kernel Panic

ftcsistemi

@ermal:

Uploaded a new kernel http://files.pfsense.org/kernel_new.gz
Beaware that you need to be updated to the latest snapshot before using this kernel otherwise you will get hangs.

the kernel is in the quote, and the snap is the latest at this time in the update manager

jimp

Just because that is true now doesn't mean that will be true in a couple hours. Timestamps are important.

As I had asked before, since things keep getting astray, does the panic I received on my Soekris board after doing this process relevant to anything or should I be ignoring it?

On the same link posted another kernel.
Thank you very much to every one helping on this.

LostIgnorance its very valuable just that this is not chat and i just do not want to spam with useless comments.

vito

No problem for testing!

so should i download just the kernel from the same link with out a snap update?
I am on snap
2.0-BETA5 (i386)
built on Wed Jan 26 09:44:03 EST 2011

Just want to make sure.

eri--

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

eri--

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.

jimp

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.

vito

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!

jimp

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

pbl

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

jimp

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…)

vito

~~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

tested one more time and it crashed again. :(

jimp

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

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

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

clahti

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

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

ya that's what I thought, thanks.
