Debian on Intel SS4000

My little nas is much happier now running Debian Linux. Many thanks to Wouter for setting it up and making sure there is official Debian support for it.

Some screenshots:

just a quick question: are the LEDs of the hard drives on your NAS active?

There don't seem to be any modules for the LEDs for the SS4000 in the default kernel.

Indeed, only the LED's at the bottom of the box are operational.

Hello, Paul
could you post "hdparm -Tt /dev/md0" from your box? I've got extremely slow system with SS4000 and 2.6.32-5-iop32x armv5tel kernel ...

Thank you in advance
