I am affected by the same bug. I use by no means new or exotic hardware. It is an ASUS P4P800SE Mainboard with an Intel 865PE Chipset. I have no problems booting kernel 2.6.19-7 and i never had this kind of problem with any previous ubuntu release. So i am suspecting a kernel bug really. Something changed with 2.6.20. I will check out my bios settings though.
