kernel-smp-2.6.18-1.2200 kernel panic

[Jason Montleon]

Good Afternoon,
I installed kernel-smp-2.6.18-1.2200 today and rebooted my computer.  I got 
a kernel panic pretty fast in the boot process.  I have 3 drives in my 
system.  md0 is a RAID 1 /boot partition formatted ext3 of appr. 1GB on hda 
and hdc.  I have a 1GB swap partition on hdc.  The remainder of the space on 
all three drives is dedicated to md1 a RAID 5 partition formatted ext3 of 
appr. 450GB.  hdb is a DVD-ROM/CD-RW.

The system boots normally with kernel-smp-2.6.17-1.2187

The error message booting with kernel-smp-2.6.18-1.2200 is (and this is 
typed by hand since it was the quickest manner I had to capture the data; 
tried to be absolutely accurate as possible, however there may be a slight 
error or two...):

  Booting 'Fedora Core (2.6.18-1.2200.fc5smp)

Uncompressing Linux... Ok, booting the kernel.

And that's all she wrote.  Any ideas?
