> =C2=A0Revert r225372:
> =C2=A0wdog_kern_pat() acquires eventhandler mutex, thus it cannot work in
> =C2=A0kernel context (from where kdb_trap() runs).
>
> =C2=A0The right way to fix this is both offering the
> =C2=A0cpu-stop-on-panic-and-skip-locking logic and also a context for KDB
> =C2=A0to officially run. We can re-enable this (or a similar) improvement
> =C2=A0when these 2 patches hit the tree.
