Description of problem: I have an AMD64 FX-55 CPU with a fresh March 1st 2006 install of rawhide. I got a lockup part way through the boot while the init scripts were starting on the first boot, but before I could get a console. There is another (new) bug that prevents me from switch to the text VT so I couldn't see any kernel messages. I hit the reset button and was able to use the box for about 50 minutes when the X server and keyboard wedged tight. I was able to ssh into the box, and dmesg gave: Slab corruption: (Not tainted) start=db669a68, len=128 Redzone: 0xdb669a64/0xdaf73069.

This is probably the Maxtor SATA II and Nvidia nforce4 incompatibility problem.
