Description of problem:
On a Dell PowerEdge 2650 with RHEL 3.0 AS, we recently ran up2date,
which installed the kernel-smp-2.4.21-20.EL package.  This kernel
crashes on our hardware, while the kernel-2.4.21-20.EL kernel boots
just fine.  The crash shows a kernel oops in what looks like the
aacraid driver.



Version-Release number of selected component (if applicable):
kernel-smp-2.4.21-20.EL

How reproducible:
Always

Steps to Reproduce:
1. Install kernel-smp-2.4.21-20.EL
2. Reboot.
3. Watch it crash with stack trace.
    

Actual Results:  Crashes every time.

Expected Results:  Normal system bootup.

Additional info:

Some more details:
 kernel package (broken): kernel-smp-2.4.21-20.EL
 kernel package (works): kernel-2.4.21-20.EL OR kernel-smp-2.4.21-15.EL
 system memory: 2GB
 system processors:  (2) 2.8GHz Intel Xeon

NOTE:  The SMP kernel crashes every time at the same place (though I
haven't been able to get a screen capture of it).  The non-SMP kernel
boots successfully every time.
