I agree about this being a possible timing issue, yesterday upgraded to 10.10 on three PCs:
Dell Latitude 640C (P4M 2.4GHz) running Kubuntu - No problem
Athlon 64 Socket 939 x2 4200, with DDR RAM running Kubuntu 64-bit - No problem
Athlon 64 Socket AM2 x2 5600, with DDR2 RAM running Ubuntu 32-bit - Problem
Both Athlon 64 systems use Adaptec SCSI controllers and 72Gb disks for the OS so the only real difference is CPU and RAM performance. I don't think 64-bit makes a difference.
