What I can't understand, is why ist he LiveCD broken, but the actual kernel works just fine.
I still am running 10.10 on my T42 (2.1 Ghz Pentium-M sans PAE or NX). I wanted to do a fresh install due to the fact that I have an PATA SSD in it, that does not support the trim command, so a full security clear is required to reset the drive to full performance. Something that I've accepted to live with for the life of this unit. And doing so every 2 years hasn't been so bad for me ;) Anyhow, I've compiled the 2.6.38.8 kernel on it and ENABLED PAE. Also installing the native 2.6.38.8-PAE kernel on this machine boots just fine! Yes, a kernel that has built in support for PAE works normally, or so it seems. The 'must have pae option' warning (which comes from the kernel itself, cpu.c) does not show. Taking this further, I booted (on a nother box) the LiveCD, added deb-src to the sources file and followed the kernel howto which installed gcc and the whole shebang into my livecd enviroment. I then compiled the 3.2 kernel twice. Once with the config from my current 2.6.38.8 kernel, saying no to all new things and ENABELING PAE. Obviously also this booted just fine. Then using the 3.2 config supplied in /boot in the live enviroment, with PAE also enabled, booted JUST FINE. So please, what happened here, that the LiveCD kernel that gets booted, does NOT work, yet any kernel I have tried using PAE works just fine on the pentium-m. P.S. I used to have the same 1.7GHz pentium-m the original bug reporter has and know for a fact, that PAE works just fine there aswell. Find attached, dmesg.log and config.log, which are | grep -i pae for 2.6.38.8 config, and dmesg_3.log, config_3.log with the 3.2 config. See this as proof that a PAE kernel does work on the pentium-m. I won't speak for pre-pentium-pro cpu's that actually fully lack pae hardware support. ** Attachment added: "2.6.38.8 /proc/config.gz | grep -i pae" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/930447/+attachment/3175563/+files/config.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/930447 Title: Unable to Install Ubuntu 12.04 on Pentium M x86 Laptop due to PAE kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/930447/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
