Anyone seeing list_add corruption running qemu-kvm with -smp 2 on Intel
hardware?
Debugging some local changes, which don't appear related. Running
module from latest git on F12.

Can you post a trace? Which list appears to be involved?

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

It's the per-cpu activated vcpu list, I'm guessing, which is why I only
see it on Intel. I'm starting a bisect. I get a reliable system crash
upon release of kvm instance. :(
Hopefully it is just a bug in my patches :)
