From 7d1849aff6687a135a8da3a75e32a00e3137a5e2 Mon Sep 17 00:00:00 2001 From: Mikael Pettersson Date: Thu, 3 Dec 2009 15:52:44 +0100 Subject: x86, apic: Enable lapic nmi watchdog on AMD Family 11h The x86 lapic nmi watchdog does not recognize AMD Family 11h, resulting in: NMI watchdog: CPU not supported As far as I can see from available documentation (the BKDM), family 11h looks identical to family 10h as far as the PMU is concerned. Extending the check to accept family 11h results in: Testing NMI watchdog ... OK. I've been running with this change on a Turion X2 Ultra ZM-82 laptop for a couple of weeks now without problems.
