From d788bada2f6c49673f85338ac4c0c642e5e52cff Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Fri, 6 Jun 2008 03:28:13 +0100 Subject: [PATCH] x86: APIC/SMP: Downgrade the NMI watchdog for "noapic" If configured to use the I/O APIC, the NMI watchdog is deemed to fail if the chip has been deactivated as a result of "noapic". Downgrade to the local APIC watchdog similarly to what is done for the UP case. Signed-off-by: Maciej W.
