Most recent kernel where this bug did not occur:

Distribution:

Hardware Environment:
CPU: Opteron 140EE

Problem Description:

I have begun to use a PC with a Motherboard named NFPIK8AA-8EKRS.
http://www.foxconnchannel.com/products_motherboard_2.cfm?pName=NFPIK8AA-8EKRS

The Board has two on-board SATA controllers,
one is called Nforce4 Professional 2200(CK8-04)
other is called Nforce4 professional 2050(I/O-4).
And each controller has four SATA ports.
Thus this board has total 8 SATA ports.

I find when a SATA Disk which FC4 is installed
is connected to a SATA ports controlled by I/O-4,
the disk is not boot without the option of "acpi=noirq".
When the Disk is connected to CK8-04,
Boot process works fine.

I have took pictures of monitor
showing error message in booting without "acpi=noirq".

I also put dmesg's
http://type-r.dnsalias.net/9usjs/dmesg.txt
http://type-r.dnsalias.net/9usjs/dmesg_noirq.txt.

Former shows the log when I connect the HDD to the port controlled by CK8-04,
latter shows one when I connect the HDD to the port controlled by I/O-4.

If further information is needed,
I will post it as much as possible.



Steps to reproduce:
1. Power off the PC
2. Connect the SATA disk to ports controlled by I/O-4. 
3. Power on the PC
