Dear List,
                I've just installed Debian Squeeze on a new Dell
PowerEdge 815.  I used the 1st full installation CD.  The machine has a
single SAS hard disk in it, plus a DVD drive.  The machine has the PERC
H200 Integrated RAID Controller in it that comes as standard.  I'm
getting the following console error message at boot (cut and pasted from
serial console).  As you can see it's very early in the process...

  Booting 'Debian GNU/Linux, with Linux 2.6.32-5-amd64'

Loading Linux 2.6.32-5-amd64 ...
Loading initial ramdisk ...
Loading, please wait...
[    7.206055] mpt2sas0: failure at 
<the rest of the boot log follows>

Does anyone have any idea what this means / if it's important / how to 
fix it?
The machine seems to work OK.
