A module called register_syscore_ops(), and was unloaded without calling
unregister_syscore_ops()
Hmm... maybe arch/x86/kernel/microcode_core.c ?
Try reverting f3c6ea1b06c71b43f751b36bd9

I was running into something similar myself and my issue was resolved in
commit 4ac5fc6a3e4d90120f292526bcaa5ee182a7411b from this morning.

I analysed your crash and came to this conclusion.
(My local linux-2.6 copy did not had the fix, like yours)
