Subject: pata_via appears to incorrectly detects 40-pin cable

I'm testing Linux kernel version 2.6.22-rc1 using Debian Testing on an Acer Ferrari 3400 Laptop. This has a VIA IDE controller with the internal HDD and DVD writer attached. The via_pata module and SCSI disk support is compiled into the kernel and the old ATA subsystem is not. At bootup the log messages state that the main HDD is detected as being connected using a 40-pin cable which causes its speed to be limited to UDMA33 rather then UDMA100, the limit of the HD.  This works fine under the old ATA system.

I've attached the output of 'dmesg', 'lspci -vvnn' and 'lshw' to this file.

Please let me know if I can provide more information and please CC me on any responses.

Many thanks,

Francis Russell
