Hi
I'm trying to use -rc2 kernel however I'm getting quite often regular kernel
panic:
Here is a BUG trace from kvm running this kernel:
(I'm building kernel with some kernel debug checks)
(Kernel is used in 64bit qemu and running 32bit Debian environment)
linux-vanilla git: 4b97280675f45c1650ee4e388bd711ecbb18c4b4
(on top of that there are few minor unrelated patches)

Here is the same trace from my native HW Lenovo T61:
I'm suspecting new debug option:
CONFIG_DEBUG_KOBJECT_RELEASE which I've recently enabled)
I've also noticed there are much older reports for this problem:
i.e. https://lkml.org/lkml/2013/3/9/3
I can trigger this bug very easily (makes 3.12-rc2 unusable for my desktop)

Yep, I see this crash 100% of the time with v3.12-rc2 and
CONFIG_DEBUG_KOBJECT_RELEASE=y with this qemu invocation and attached
q35-chipset.cfg:
/usr/local/bin/qemu-system-x86_64 -M q35 -readconfig ./q35-chipset.cfg
-enable-kvm -m 512 -drive file=ubuntu.img,if=none,id=mydisk -device

Someone is doing something quite bad in the kernel, and as yet I've not
figured out a way to track it down.
The issue is this: someone is kfree'ing a kobject before its release
function has been called, and the memory is being re-used. The problem
is that when the last reference has been dropped with the debug enabled,
the kobject is linked into the timer lists for the delayed work. When
the timer lists get run, they're found to be corrupted.
The obvious solution to this is to move the delayed work out of the
kobject into a separately allocated structure. That would work if
x86 didn't register kobjects very early in boot, before the memory
allocators were up and running.
Frankly, I've no idea how to solve this. So I regard x86 as just being
difficult and broken. :)
If anyone has any ideas, then I'm all ears.
