Hi all,
Just tested the new CentOS 6.8 release on a few VMs and a physical box and got a kernel panic.
Is it just me, or anybody else as well?
Just fishing for now, will look into the issue more thoroughly later today.

Include the actual kernel panic you're seeing, along with the hardware you're running it on, or this thread is going nowhere.

Hi and thanks for the reply.
It was a general question, therefore no details (yet).

Did you see it in every case or just one case?
That kernel has been out there since May 16, 2016 (in CentOS CR, 10 days):
https://lists.centos.org/pipermail/centos-cr-announce/2016-May/002855.html
There are a couple issues with that kernel on an internet search:
https://access.redhat.com/solutions/2314491
https://github.com/ntop/PF_RING/issues/96
https://www.virtualbox.org/ticket/15411
https://bugzilla.redhat.com/show_bug.cgi?id=1333697
But I don't see any other issues in either the Red Hat or CentOS bugs databases and none of those are oops.

Hi,
Of the four machines tested, two failed with a kernel panic. At the time, I just rebooted to a previous kernel, as a quick fix.
I found some of the issues you list already.
I've run the CR-updates on a few test-machines since they became available and have had no problem. Weird...
I've tested some more now, and it seems the upgrade went fine on my Virtualbox Win7-host for the test-guests. No kernel-panic, all seems well. The ones that failed were all Hyper-V guests. I need to pick a sacrificial physical computer and see if it's reproducible.
For now, trouble-shooting and testing on Hyper-V as I write this.

Thanks for the feedback.
Right now I'm looking at the specific Hyper-V guest I saw the kernel panic on before. There might be some weirdness going on with NFS, need to test some more though.
The other test-guest on Hyper-V I upgraded to CentOS 6.8 initially had a problem booting up, but a reset seems to have fixed. Works fine now.

If lockd is failling to start:
Uninstalled NFS, as it wasn't needed anyway.
Still got the panic.

I haven't been following this thread closely, but if it's 7, have you tried booting it from a rescue (pxe/dvd/usb key), and running journalctl?

Hi!
It's CentOS 6.8., but I'll keep your hint re 7 in the goodie-bag.
Thanks.

Seriously, what panic?
The one I posted a screen dump of earlier.

I don’t see any posts of a screen dump. The mailing list software (mailman) is set to strip any non-text attachments, so if it was an image, it was probably stripped.

Oh, wasn't aware of that. My apologies.
Screendump available here: https://uppsala.box.com/s/iwoh20xsayywbetfdd7uh8vs6hcpmqxt
To recap, the problem was with the linux integration services. Uninstalling them, updating the guest as usual and then rebooting the guest, fixed the panic. Haven't seen this problem before.
