I'd noticed this deprecated option ("conflicts with libata") but never
bothered to track down where libata is enabled.
It's in the SCSI low-level drivers as you said.

Before:
Timing cached reads: 2732 MB in 2.00 seconds = 1365.53 MB/sec
Timing buffered disk reads: 10 MB in 3.04 seconds = 3.29 MB/sec
After:
# hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 2664 MB in 2.00 seconds = 1330.21 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate
ioctl for device
Timing buffered disk reads: 164 MB in 3.00 seconds = 54.60 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate
ioctl for device
Got to be happy with that!
I don't know what that other message means - see below
Here are the missing config options:
---------------------------------------------------------------
[EMAIL PROTECTED]:/home/htpc# diff config config.old|grep -v \#
(snip)
---
667,681c667
< CONFIG_SCSI_SATA=y
< CONFIG_SCSI_ATA_PIIX=y
< CONFIG_SCSI_SATA_INTEL_COMBINED=y
---
---------------------------------------------------------------
Slight problem:
# hdparm -i /dev/sda
/dev/sda:
HDIO_GET_IDENTITY failed: Inappropriate ioctl for device
I'll be looking into this.
Apart from this everything was fine at the first reboot. No errors.

That's twice in one day you read my subconscious correctly. Spooky.
Thanks again
