Description Mathijs Kwik 2007-02-04 16:26:40 UTC

Some mainboards with intel's ICH8 chipset don't use ascending names/numbers for their SATA-ports.

Mine has sata1 sata2 sata5 and sata6 for example.

The AHCI driver stopped checking after sata3 (non-existing), so 2 of my sata-ports were never checked.

Fortunately I found a patch in 2.6.20 that fixes it, so I backported it to 2.6.19.

Can someone please include this in gentoo-sources?

Reproducible: Always

Steps to Reproduce:
1. boot PC
2. ls /dev/sd*


Actual Results:  
/dev/sda  /dev/sdb 

Expected Results:  
/dev/sda  /dev/sdb  /dev/sdc  /dev/sdd
