From d44647b0a6e48d18a1402dfa9052d85c4fe98341 Mon Sep 17 00:00:00 2001 From: Andy Currid Date: Thu, 8 Jun 2006 00:43:38 -0700 Subject: [PATCH] Fix HPET operation on 32-bit NVIDIA platforms From: "Andy Currid" This patch fixes a kernel panic during boot that occurs on NVIDIA platforms that have HPET enabled. When HPET is enabled, the standard timer IRQ is routed to IOAPIC pin 2 and is advertised as such in the ACPI APIC table - but an earlier workaround in the kernel was ignoring this override. The fix is to honor timer IRQ overrides from ACPI when HPET is detected on an NVIDIA platform.
