Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, While my friendly dual Xeon machine now appears to be pretty fast, I notice that the NMI counter is still incrementing like topsy; this presumably means that there is still something dodgy going on. A hdparm -t seems to be giving respectable values, so I am not quite sure where the time/performance is going: /proc/mtrr shows the following reg00: base=0xf9f00000 (3999MB), size= 1MB: uncachable, count=1 reg01: base=0xfa000000 (4000MB), size= 32MB: uncachable, count=1 reg02: base=0xfc000000 (4032MB), size= 64MB: uncachable, count=1 reg03: base=0x00000000 ( 0MB), size=4096MB: write-back, count=1 reg04: base=0x100000000 (4096MB), size= 64MB: write-back, count=1 reg05: base=0x104000000 (4160MB), size= 32MB: write-back, count=1 reg06: base=0x106000000 (4192MB), size= 1MB: write-back, count=1 Here are two /proc/interrupts straight after each other: CPU0 CPU1 0: 14047275 17655700 IO-APIC-edge timer 1: 73 37 IO-APIC-edge keyboard 2: 0 0 XT-PIC cascade 9: 0 0 IO-APIC-edge acpi 12: 1196 928 IO-APIC-edge PS/2 Mouse 13: 0 0 XT-PIC fpu 20: 226485 240634 IO-APIC-level eth0 56: 14 16 IO-APIC-level sym53c8xx 57: 52554 55135 IO-APIC-level sym53c8xx 58: 15 12 IO-APIC-level sym53c8xx NMI: 31702796 31702796 LOC: 31702834 31702833 ERR: 0 CPU0 CPU1 0: 14047328 17655766 IO-APIC-edge timer 1: 73 37 IO-APIC-edge keyboard 2: 0 0 XT-PIC cascade 9: 0 0 IO-APIC-edge acpi 12: 1196 928 IO-APIC-edge PS/2 Mouse 13: 0 0 XT-PIC fpu 20: 226496 240646 IO-APIC-level eth0 56: 14 16 IO-APIC-level sym53c8xx 57: 52554 55135 IO-APIC-level sym53c8xx 58: 15 12 IO-APIC-level sym53c8xx NMI: 31702915 31702915 LOC: 31702953 31702952 ERR: 0 Thats 2.4.0-test10 with last weeks patch.
