Problem with upgrading Fedora 11 to Fedora 12.

Hi All,
I have been using fedora 11 and just wanted to move to fedora 12.After doing search on google I found the commands to upgrade it.
1- yum update rpm
2- yum -y update
3- yum install preupgrade
4- preupgrade

All the updated went on smoothly but on rebooting the system after executing the "preupdrade" command, system is not able to boot.
Below is the snasphot of the error that i am getting:
Netlabel: Protocol=unlabeled CIPSOV4
Netlabel: Unlabeled Traffic Allowed by Default
DMAR: Host Address with 36
DMAR: DRHD Base:0x0000000000000000 Flags:0x1
IOMMU 0: ver 5:3 cap f0003d6cf000e2c3 ecap f000ff54f000ff53
DMAR:RMRR Base: 0x000000bde00000 end:0x000000bfffffff
DMAR: No ATSR found
DRHD: Handling Fault Status Reg f0003d60
Kernel Panic Not syncing: DMAR Hardware is Malfunctioning
PID:1, COM: Swapper Tainted:G W #1

Can anybody please help me in resolving this issue ?

No, I don't have the disc for this. I tried to upgrade it online.
