Fedora 12: Cannot boot with kernel-2.6.32.9-67.fc12.x86_64

[Steven P. Ulrick]

Hello Everyone
The good news is that in my 10+ years using Linux, I am almost certain that 
I have never had a kernel that would not boot...

Last night I ran "yum update" and it pulled in 
kernel-2.6.32.9-67.fc12.x86_64.  When I attempted to boot it, the boot 
process seemed to complete, but X never started.

Since I have never had this problem before, I don't know precisely what 
information that you need.

I am running an NVidia video card, with the proprietary NVidia driver, 
installed from RPMFusion.  After failing to boot 
kernel-2.6.32.9-67.fc12.x86_64, I can reboot and choose another kernel and 
it boots just fine.

From /var/log/messages, this is the closest that I can find to anything 
relevant:
Mar  8 03:01:56 localhost kernel: DRHD: handling fault status reg 102
Mar  8 03:01:56 localhost kernel: DMAR:[DMA Read] Request device [03:00.0] 
fault addr 233038000 
Mar  8 03:01:56 localhost kernel: DMAR:[fault reason 01] Present bit in 
root entry is clear
Mar  8 03:01:56 localhost kernel: NVRM: Xid (0003:00): 54, CMDre 00000000 
00000000 00000000 00000001 00000001
Mar  8 03:01:56 localhost kernel: DRHD: handling fault status reg 202
Mar  8 03:01:56 localhost kernel: DMAR:[DMA Read] Request device [03:00.0] 
fault addr 235833000 
Mar  8 03:01:56 localhost kernel: DMAR:[fault reason 01] Present bit in 
root entry is clear
Mar  8 03:01:56 localhost kernel: NVRM: Xid (0003:00): 6, PE007e 
Mar  8 03:01:56 localhost kernel: DRHD: handling fault status reg 302
Mar  8 03:01:56 localhost kernel: NVRM: Xid (0003:00): 6, PE007e 

Again, I can boot fine from every other kernel.  I just can't boot from 
2.6.32.

If all I need to do is try running without the proprietary NVidia driver, 
please let me know specifically how to disable that driver the easiest 
possible way.  Translation: so that I can just boot back into an older 
kernel and continue using the proprietary NVidia driver if I decide to do 
that.

Also, not only have I never had a problem with being able to boot a 
particular kernel, I have never had any problems with the proprietary 
NVidia driver.

Let me know any additional information that you may need to help me with 
this issue.
