We want to be sure that Ubuntu is fully compatible with the new Intel Core 2 Duo Processors.

Problems

Installer Freezes on Not Finding IDE CD/DVD-ROM Drive

I believe this is caused due to the Intel P965 chipset has no more integrated IDE channel, thus the motherboard usually has an additional chip onboard for an IDE channel. In the current Gigabyte (I got one of them) and ASUS (think they have it too) this is a JMicron JMB363. Until very recently the kernel had a bug inside that made it unable to access the IDE/PATA channel. So If you have and IDE drive or HDD left you will not be able to use it.

I would guess most people have a SATA drive with such a new computer. The trick to it is then to avoid the PATA CDROM for installation (though the BIOS can boot off it). Utilising USB sticks, you can do the following:

Either of these methods has worked for me just fine.

Fixed in Edgy Status/Notes

I tried Kubuntu Knot 2 tonight with no luck. It got to the start screen, and hit install and it freezes to a blank screen with a blinking cursor at the top left of the screen.

I've managed to get the edgy kernel to recognize my PATA drives by compiling in the disk controller modules and passing all-generic-ide at boot. I'm not sure yet if all of the ide modules have to be compiled in, or just ide-generic. From dmesg, it looks like ide-generic has to be initialized before anything else in order for this to work (which is why it can't be compiled as a module). Maybe somebody can figure out how to do this with the initrd, but for now compiling in ide-generic works for me. This works on 2.6.17.11, compiled from the git tree. I haven't tried the dapper kernel yet.

I tried Ubuntu Knot 3 ("Edgy Eft" - Alpha amd64 (20060915.1)) today with the "all-generic-ide" option without success. Unfortunately it seems that the patch from Alan Cox is not yet included in the kernel on the disc.
