I can't get my hd to run in udma5 or 6, only 2. Here's my setup:
It's a Seagate 160GB SATA drive running on the Intel ICH5 controller (82801EB).
My controller:
| Code: | bash-2.05b# lspci | grep IDE
00:1f.2 IDE interface: Intel Corp. 82801EB Ultra ATA Storage Controller (rev 02)
|
My drive:
| Code: | bash-2.05b# dmesg | grep hda
hda: ST3160023AS, ATA DISK drive

hdparm -I
| Code: | hdparm -I /dev/hda

hdparm -v
| Code: | bash-2.05b# hdparm -v /dev/hda
/dev/hda:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 19457/255/63, sectors = 312581808, start = 0

Doing hdparm -X udma5 /dev/hda has no effect on this output. The result is that Gentoo takes 1 minute 36 seconds to boot, whereas Windows XP takes 26 seconds (from selection in Lilo to completely calm).
Any idea why? Happy to post any other configs/tests needed. I'm running 2.6.4-rc1 (my config). I was having this same problem with 2.4.22, but I read SATA support is much better in 2.6. In 2.4.22 I couldn't even enable DMA on my drive (HDIO_SET_DMA failed error). |
