On my production machines I'm running Debian Etch, because I prefer the stable Debian tree. It runs great, but there is just one problem: the 2.6.18 kernel is a bit outdated nowdays since it does not support all the latest hardware, like newest motherboards based on Intel P35 chipset.
ASUS P5K series is a good example. The problem with this board is that 2.6.18 kernel which comes with Debian Etch by default does not support both SATA controller and NIC of ICH9.
Of course, I can always download & compile the latest 184.108.40.206 sources and install it on my Debian Etch box. But there is a better solution now, thanks to Kenshi Muto who has created and supports the archive of backported Debian-installer images.
The latest addition is Debian Etch with 220.127.116.11 kernel and experimental e1000e driver. I've successfully installed it on my machine with ASUS P5KR motherboard and it runs great! Both ICH9 SATA controller and Attansic L1 NIC work well.
