Re: [Xen-devel] [PATCH] x86/nmi: Make external NMI injection reliably crash the host

On 08/26/14 06:10, Ross Lagerwall wrote:
Change the watchdog handler to only "tick" if the corresponding perf
counter has overflowed; otherwise, return false from the NMI handler to
indicate that the NMI is not a watchdog tick and let the other handlers
handle it.  This allows externally injected NMIs to reliably crash the
host rather than be swallowed by the watchdog handler.

If a crash kernel has been setup via kexec, does this change to
"crash host" ends up jumping into the crash kernel?
