I too have had this issue and found that by simply upgrading the bios to the latest version (build 332), the system performed above and beyond expectations in both single and dual channel configurations.
While installing with a single channel configuration works, the system still won't be performing at its best.
Also, once you've gone back to dual channel configuration after installation, you'll probably find that the system will still come to a grinding halt during the boot process of linux.
For a Genuine Intel mainboard, download the latest bios here:
