[opensuse-kernel] 3.10rc2 crash
Hi, I see this in openqa tests and rc2 seems to be fresh enough not to go through bugzilla queue with it. It doesn't seem to be fatal even though it says panic, but I thought you may get something out of it.

Ohh boy, crashing while taking a crashdump is a bit ironic, isn't it. Where can I find vmlinux for that kernel? Could you make it awailable or point me at the rpm package, please?

Hmm. It's weird -- ffffffff81031d62 is a retq instruction.

Hi,
This is kernel-desktop-3.10.rc2-1.1.gd28ac96.x86_64, which is the rpm you can find at http://download.opensuse.org/factory/repo/oss/suse/x86_64/
OK, that looks a bit saner.

Btw. what was the previous warning that tainted the kernel?
