Thanks ,goot night .

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.

Here is a link to the commit:

I pulled the linus' tree ,then it goes well .
The issue is seems like you said ,unregister the syscore_ops But , can you tell me how did you know that ?

Thanks

I analysed your crash and came to this conclusion.

(My local linux-2.6 copy did not had the fix, like yours)

It fixed now .
Just pull your tree .
cheers.
Thanks
