Guys, After a kernel rebuild my machine was pretty fast! =D
My new config: cat /usr/src/linux/.config | grep -i cpu # CONFIG_GENERIC_CPU is not set CONFIG_X86_CPUID=y CONFIG_SPLIT_PTLOCK_CPUS=4 # CPU Frequency scaling CONFIG_CPU_FREQ=y CONFIG_CPU_FREQ_TABLE=y # CONFIG_CPU_FREQ_DEBUG is not set CONFIG_CPU_FREQ_STAT=y # CONFIG_CPU_FREQ_STAT_DETAILS is not set CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y # CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set CONFIG_CPU_FREQ_GOV_PERFORMANCE=y # CONFIG_CPU_FREQ_GOV_POWERSAVE is not set # CONFIG_CPU_FREQ_GOV_USERSPACE is not set # CONFIG_CPU_FREQ_GOV_ONDEMAND is not set # CONFIG_CPU_FREQ_GOV_CONSERVATIVE is not set # CPUFreq processor drivers # CONFIG_X86_ACPI_CPUFREQ is not set # CONFIG_X86_ACPI_CPUFREQ_PROC_INTF is not set Since I'm running a desktop machine, not a laptop, I removed all non related options. Chris, no problem with my DMA:
hdparm /dev/hda
/dev/hda: multcount = 16 (on) IO_support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 65535/16/63, sectors = 156250000, start = 0 Thanks for all tips everybody! On 4/27/06, Chris Wall <[EMAIL PROTECTED]> wrote:

I always get tripped up by this between an Intel 2.53 machine and my AMD64 3200+ machine. It seems that everytime I rebuild the kernel on the AMD64 I forget to set the correct values for DMA access.
