Description:   Opened: 2005-10-10 11:48 0000 
I'm running an AMD64 system with 16GB of RAM. Booting the 2005.1 Universal
LiveCD via a USB CD-ROM device, I note a warning that 32-bit PCI device support
may be unreliable due to running with >4GB RAM on a kernel lacking IOMMU
support, followed by an Oops in khubd, leading to said USB device being
unavailable to chroot to. Booting with mem=2048m works around the issue.

Perhaps amd64 LiveCDs should have kernels with IOMMU support?

Reproducible: Always
Steps to Reproduce:
1. Boot off 2005.1 Universal LiveCD via USB drive on amd64 system w/ >4MB RAM
2. Watch it fail to boot. Press enter to get a shell when prompted for root device.
3. Run "dmesg". Observe warning (that PCI devices may not work correctly w/ >4GB
RAM and no IOMMU support) and Oops.

This is fixed with the 2005.1-r1 release media.
