2.6.17-1.2614 --> ICH8 SATA not working

[Fernando Herrera]

Hi,

After upgrading rawhide kernel from 2.6.17-1.2608 to 2.6.17-1.2614 my
SATA hard disk is not recognized anymore.

The motherboard is a ASUS P5B with an Intel ICH8 controler and a
JMicron JMB363. The only way to get the drive recognized by the kernel
(2608) is setting the BIOS SATA configuration in IDE mode (instead of
AHCI).

Here is an extract of dmesg working with kernel 2608:
