Package: linux-2.6 Severity: normal
I recently purchase a pc with a dual-core AMD64 cpu and Asus M3A78 Pro motherboard. I experienced very poor disk i/o performance and filesystem corruption when I enabled the BIOS option ACPI APIC Support, to the extent that an ext3 filesystem had unrecoverable errors. The BIOS manual describes the option: "ACPI APIC Support" When set to enabled, the ACPI APIC table pointer is included in the RSDT pointer list. Since I've disabled "ACPI APIC Support" I have had no hard disk i/o problems, but since the patch http://patchwork.kernel.org/patch/1473/ has been applied to the kernel source, the kernel has disabled the use of the second CPU core. I've backed out that patch and recompiled the kernel to make both CPU cores available, but would rather a fix that doesn't require manually patching the kernel source. -- System Information: Debian Release: squeeze/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.29 (SMP w/2 CPU cores; PREEMPT) Locale: LANG=en_AU.UTF-8, LC_CTYPE=en_AU.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
