Hi, I have much trouble to get sata working with an Intel 82801I (ICH9 Family) interface from a Compaq dc5800. The minimal CD 2008.0 uses the ata driver and not sata so harddisks are registered as /dev/hda. After installation, my custom kernel does the same and I had to disable ata completely (CONFIG_IDE) before the sata driver was loaded correctly. (followed thread: http://bugs.gentoo.org/show_bug.cgi?id=184825)
Now the sata driver loads correctly (it seems) but my hardisk is extremely slow: /dev/sda: Timing cached reads: 3746 MB in 2.00 seconds = 1874.11 MB/sec Timing buffered disk reads: 6 MB in 3.20 seconds = 1.88 MB/sec while when CONFIG_IDE is set, I have the following performace with the ata driver: /dev/hda: Timing cached reads: 7550 MB in 2.00 seconds = 3779.94 MB/sec Timing buffered disk reads: 14 MB in 3.46 seconds = 4.05 MB/sec Any idea on what I can try to do next? Some more info on my setting below. Thanks for any suggestion, David My .config is at http://pastebin.ca/1296359 grub.conf: title Gentoo Linux 2.6.26-r4 root (hd0,1) kernel /boot/kernel-2.6.26-gentoo-r4 root=/dev/sda5 dmesg: 3ware Storage Controller device driver for Linux v1.26.02.002.
