Subject: kernel BUG at /src/linux-bcache/kernel/smpboot.c:134!

Hi Thomas and everyone else,

I saw in a thread last year you fixed a similar (or same?) bug as the
subject[1]. However I can still reproduce this issue using kernels
that have your patch in them. I filed a bug with qemu[2] containing a
repro (just boot a VM with multiple CPUs and init=/sbin/reboot and let
it cycle) but after finding the above thread I'm not convinced its a
qemu issue anymore.

Any ideas?

Slava
