Subject: RE: [RFC][PATCH] Add a sysctl option controlling kexec when MCE occurred
Date: Thu, 23 Dec 2010 12:31:24 -0500 [thread overview]
Message-ID: <5C4C569E8A4B9B42A84A977CF070A35B2C132F6BB0@USINDEVS01.corp.hds.com> (raw)
In-Reply-To: <20101223091851.GC30055@liondog.tnic>
Hi,
I agree with Borislav that kexec shouldn't start at all because we can't guarantee
a stable system anymore when MCE is reported.
On the other hand, I understand there are people like Andi who want to start kexec
even if MCE occurred.
That is why I propose adding a new option controlling kexec behaviour when MCE occurred.
I don't stick to "sysctl".
I suggest to add a new boot parameter instead of sysctl because users can't change
their configuration once the boot parameter is set.
I will resend the patch if it is acceptable.
Regards,
Seiji
