I recently downloaded and built a live usb of the latest 12.04 daily build iso for i386 hardware using the following link address: http://cdimage.ubuntu.com/daily-live/current/precise-desktop-i386.iso. I was not able to boot from the live usb due to the incompatibility of the linux kernel on the 12.04 iso and my Pentium M laptop hardware.

The error message I received is as follows: "This kernel requires the following features not present on the CPU: pae. Unable to boot - please use a kernel appropriate for you CPU." I expected that I would be able to install Ubuntu 12.04 on my IBM Thinkpad T42 laptop that has a Pentium M processor, 1700Mhz processor. The root cause of the issue appears to be that the default kernel bundled in the current daily build i386 iso is the generic-pae kernel. It's my understanding that the generic-pae kernel cannot be installed on cpu hardware that does not support pae.

I have been using Ubuntu since 10.10. I have been able to install 10.10, 11.04, and 11.10 on my Thinkpad without issue. My understanding of the December Tech Board kernel meeting is that the non-pae kernel will be supported until 12.10. If that's the case, there should be a version of the Ubuntu 12.04 iso available for download that can be loaded on non-pae hardware.
