2.6.10-rc1 & ahci & IHC6R & 925X & raid1

From: Matthijs Melchior
Date: Sat Oct 23 2004 - 10:54:07 EST


Hi,
Linux running on my new Dell-8400 computer does not recognize
the SATA disks [No problem with the PATA drives].
The attached log is output from 'dmesg' with '/proc/modules'
and 'ps -Hel' appended.

This machine has 4 disks, configured in the Intel Raid configuration
BIOS as 3 devices, with disks on ports 0 & 2 being a raid1 pair,
half of disks 1 & 3 also a raid1 device and the rest a raid0 device.
The raid signatures on disk 3 have been removed [for testing].

Ths "SATA Operation" setting in BIOS is set to "RAID Autodetect / AHCI".


I have set symbols ATA_DEBUG and ATA_VERBOSE_DEBUG to 1 for more output
and built a new set of modules.

I have configured netbooting [PXE] for this machine and I can boot
the kernel with an initrd. The only thing it currently does is loading
usb modules for console, usb keyboard, network and starting a shell.

Giving the command "modprobe ahci" hangs the machine.

Using "modprobe ahci &" instead and investigating the state at that
time leads me to suspect ata_dev_identify() waits for an interrupt that
is not occuring.

The attached '/proc/modules' and 'ps -Hel' are from this environment.

Please, can someone help me debugging this further, what other info
would be usefull, are there other experiments that can provide new
insights into this problem.....
