[PlanetCCRMA] more disk performance problems

[jfm3]

Sorry to take a while to get back on this one.

I see no different module names under the 2.6.12 FC4 1447 kernel than I
do under the 2.6.13 ccrma kernel.

I'm pretty sure this is the releveant lspci entry under 2.6.12.

00:1f.2 IDE interface: Intel Corporation 82801FBM (ICH6M) SATA
Controller (rev 03) (prog-if 80 [Master])
        Subsystem: Dell: Unknown device 0187
        Flags: bus master, 66Mhz, medium devsel, latency 0, IRQ 7
        I/O ports at <ignored>
        I/O ports at <ignored>
        I/O ports at <ignored>
        I/O ports at <ignored>
        I/O ports at bfa0 [size=16]
        Capabilities: [70] Power Management version 2

Anyone else using SATA disks under 2.6.13 ccrma?
