Oracle Linux 6.4 kernel 3.11 giving panic on startup

Hi,
Hi just upgrade my Oracle Linux 6.4 to kernel 3.11. The upgrade process went fine, but now when I try to boot my Linux, I am getting kernel panic.
I am using Oracle VirtualBox 4.2.18 under MS Windows7.
Any help would be very appreciated.
Regards

Where did you get this kernel, and the supporting dev and header packages?

I just ran yum update and it updated my Oracle Linux 6.4 with this new kernel.
================================================================================
Package Arch Version Repository Size
================================================================================
Installing:
kernel x86_64 3.11.1-3.11.y.20130924.ol6 ol6_playground_latest 25 M
kernel-devel x86_64 3.11.1-3.11.y.20130924.ol6 ol6_playground_latest 8.7 M
It is my understanding that Oracle has been tested it before release it to the community user.
I am still able to access my Linux box, but using old 2.6X kernel version. Always I boot my Linux using version 3.11, it crashed at boot.
Regards.

So you added the Arch repo to Oracle Linux. Mixing repos is never a good idea. You should have added the Oracle public repo.
http://public-yum.oracle.com/
I suggest that you boot to the proper kernel and remove the 3.11 kernel and its packages, remove the Arch repo and add the proper one.
Hopefully this will take care of your issues so you don't need to rebuild the guest.
In any case this has nothing to do with VirtualBox.

I did not mixed the repos. I am using the Oracle public repository. Yes, of course the issue is not on Virtual box side. I just opened this thread to see if anyone else already had this issue and fixed it. Actually, everyone using Oracle 6.4 Linux running under VirtualBox wanna to face the same issue, when they run the kernel upgrade.
I will try to found a solution / workaround for this in Oracle Linux forums.
Regards.

As you can see the kernel that is the newest in the public repo is 2.6.39 I am not sure where you are getting 3.11 but it is not in the OEL public repo.
Code: Select all
[oracle@localhost etc]$ sudo yum update

I see where you must be using the "Oracle Linux Playground yum repo" which is not really the main line repo and is intended for testers and kernel developers to see the what's and hows. So yes the best place would be the Oracle playground forums.

I added the Playground repo and installed 3.11 which works for me. You need to pay attention to packages that are conflicted with the new kernel though. I had to remove php* and it did panic at the first warm boot. I believe this has to do with timing but a cold boot does bring it to life. Remember though that the official guide states this is not for production.
