Description of problem:
I have an Abit UL8 motherboard, x86-64 Socket 939, with a AMD64 3200+ CPU with
2GB (2x1GB PC3200 DIMMs) of memory.  I recently upgraded from a 40GB (Seagate)
UATA drive to a 250GB SATA (Maxtor) drive and tried to do a reinstall.
While formatting the HD I get kswapd kernel crashes. I can perform a successful
install if I limit the memory artificially using mem=768M at boot time.
Kernel Panic. In the previous install it uses the UATA drivers, in the new
install it uses the uli-sata libsata driver.

Version-Release number of selected component (if applicable):
2.6.11 kernel on install disk during format, and 2.6.13 kernel from updates
(post MEM=768M) crashes while doing a yum update.

How reproducible:
Everytime

Steps to Reproduce:
1. Use an Abit UL8 with uli-sata drivers
2. Install on a SATA hard drive (250GB)
3.
  
Actual results:
Kernel Panic while formatting using default settings (LVM).

Expected results:
Installation successful.
