Hi there,
I contact you because I encountered some issues regarding the 2.6.24
kernel and my ICH7 controller.
I'm using an Asus P5W-DH with 2 hard drives plugged on the SATA port 1
and 3 and a DVD writer on SATA port 4.
My Jmicron controller is disabled.
The problem appears since I've bought that motherboard but wasn't really
a major issue (when using a 2.6.20, everything works fine, using a
2.6.22 forced me to unplug my dvd writer to boot properly, now with
2.6.24, my dvd writer is working but handles for a while on boot)
Here is the dmesg result :

As you can see, the second sata port handles the system for a while. The
2nd port seems to be used as a bridge for the jmicron controller (I'm
not sure about that).
But, this bug has been marked for being fixed on the kernel 2.6.23
(http://bugzilla.kernel.org/show_bug.cgi?id=8923)
I configured the Controller for being in AHCI mode (dmesg printed
above), I also tried in IDE standard with compatible mode but it doesn't
boot in that mode.
I'd like to say I'm on an Ubuntu systems (Hardy RC) but this problem
occurs with a compiled kernel 2.6.24, so I think it's not Ubuntu related)
My 2 drives :
Seagate HDD SATA2 ST3320620AS
WD HDD SATA2 WDC WD2500KS-00MJB0
So my final question is : as this bug has been maked as fixed in 2.6.24
kernel, is my problem a new one or the patch has been applied later and
I should wait ?
Don't hesitate to ask me further information and for more tests.
