Description of problem:
Running kernel-2.6.5-1.358 or kernel-2.6.5-1.358smp, fdisk -l
correctly shows my two harddrives:

Disk /dev/hda: 100.0 GB, 100030242816 bytes
16 heads, 63 sectors/track, 193821 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
 
   Device Boot      Start         End      Blocks   Id  System

/dev/hda2   *       31209      193821    81956952    7  HPFS/NTFS
 
Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
 
   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1         653     5245191    7  HPFS/NTFS

When running kernel-2.6.9-1.3 or kernel-2.6.9-1.3smp, /dev/sda is no
longer there.

/dev/hda is a 100 GB WD drive
/dev/sda ia a 250 GB Hitachi (SATA) drive

Version-Release number of selected component (if applicable):
kernel-2.6.9-1.3

How reproducible:
Always

Steps to Reproduce:
1. Boot w/ kernel-2.6.5-1.358(smp)
2. fdisk -l
3. Boot w/ kernel-2.6.9-1.3(smp)
4, fdisk -l
