I have bought a new Mac Mini, and would like to use it as a Linux server. Now I'm trying to install CentOS on it. I downloaded CentOS-6.4-x86_64-netinstall.iso and booted the Mac Mini from a USB-stick.
But during the installation process I get these errors:
dmar: No ASTR found
IOAPIC id 0 under DRHD base 0xfed9100
HPET id 0 under DRHD base 0xfed91000
Enabled IRQ remapping in x2apic mode
Enabling x2apic

Kernel panic - not syncing: No mapping iommu for ioapic 2
Pid: 1, comm: swapper Not tainted 2.6.32-358.el6.x86_64 #1

Any suggestions what the problem is? Do I need a different binary to be able to run on an Mac?
According to a tweet, CentOS 6.4 seem to work, at least on older, Mac Mini's: https://twitter.com/courtneycotton/statuses/312267424605036544
UPDATE: the suggestion of adding noapic to the boot took me further in the installation process.
Now I had to select an installation medium. The choice is CD/DVD, Hard drive, NFS directory or URL, and I have a USB-stick, so I choose Hard drive.
Then I'm supposed to choose a partition that holds the installation image for CentOS, the choice is between /dev/sda1, /dev/sda2, /dev/sda3 or /dev/sdb1. Here I have really no idea what name my USB-stick has. I have tried with them all, but if I choose e.g. /dev/sdb1 I later get the message:
The installation source given by device ['/dev/sdb1'] could not be found. Please check your parameters and try again.
I put my iso file on the USB-stick by following the Ubuntu instructions.
Any suggestion on how to go further in the installation process?

Since the netinstall ISO was downloaded, it doesn't contain any actual packages for the installation. By choosing Hard Drive, what you're trying to say to the installer is "I have a hard drive that contains all of the installation packages." Being a netinstall ISO, you'll want to pick URL, and then specify a URL from which the packages can be obtained, by way of repository, such as http://mirror.centos.org/centos-6/6/os/x86_64/
This will pull down the installer image and set up a repository for installation, completely over the internet. You could also use an internal URL if you have a local repository.
