cannot boot into live desktop or installer in 10.10

[André Carvalho]

This bug is actually plaguing my computer since 10.04, and it's still there in 10.10 beta (1?). The problem is that I can boot off the Live CD/DVD, all fine and good. I choose my language (Portuguese-PT) and then I go and select either "Install Ubuntu" or "Try Ubuntu without installing". I get 3 messages, these sometimes are different, but they are related to "Disabling IRQ's". It disables 28, 29 and then 25. In 10.04 it disabled 31 and 32. Then the screen turns off completely. It isn't showing black, it's turned off. There is HDD activity as well as CD/DVD activity for a while (roughly 1 minute) and then it stops. The system is "dead".

I then read the release notes for 10.04 and it said something related to "nodomoset" in the "advanced options". It sort of works. I still can't boot to the installer directly, but I can boot the Live CD/DVD. In 10.10 alpha 3 I managed to get to the desktop itself but it froze 5 minutes later. In the beta I got to a console where I should type some commands, such as the one to start X. I tried to type something but the system didn't respond. So far the only thing I can do is force shutdown.

Please could you check if this issue is still occurring with latest stable release of Ubuntu Maverick? Thanks

I did a short while ago. it didn't boot unless if I added the flags "noacpi" and "nolapic". It booted and installed but it was useless afterwards. (I did edit the grub config file to add the flags to the boot option). CPU load was stuck at over 80% (idle) and it only detected one core of the CPU.

Little update I managed to find out: Ubuntu 9.10 works fine, I upgraded to 10.04 and booted its kernel and it didn't boot. I went back to the old 9.10's kernel (2.6.31-22-generic-pae according to uname -r) and it booted fine. I then upgraded to 10.10 and its kernel still doesn't boot. Again, 9.10's works like a charm, in fact I'm using it in my current Ubuntu 10.10 with the most recent nVidia graphics drivers (v. 260?)

I then thought: "what if it's a general kernel issue and no kernel newer than 2.6.31 works on my laptop?" So I downloaded an .iso image for another distribution, OpenSUSE, the most recent stable release (11.3), and it works just fine. It's kernel version seems to be 2.6.36, according to http://software.opensuse.org/search?q=kernel-desktop&baseproject=openSUSE:11.3&exclude_filter=home:&exclude_debug=true

I'm not sure if this means anything to you, but I thought It'd be good to share the knowledge.
