There must be a way to switch to non-pae?
That said I'm having no kernel related problems with this pae kernel ............ or not that I can tell so far.
I encountered a lot of bugs during Alpha 2 iso-testing and I wondered about the pae kernel, but none of those bugs turns out to have been kernel related.
So I'm thinking this new pae kernel is fine, just new and different
If someone has a kernel related bug they should report it.
OTOH, I've never had any trouble with the pae kernel, and I've been using it since it first started being installed (Lucid? Maverick? don't remember). I sure wouldn't worry about it. If push came to shove, just delete the pae kernel (making sure you have the vanilla kernel installed first).
If you think I am lying, please read:
The reason they say 'Precise' is listed on them is:
See, it specifically says it most likely will work with older releases... Not 'nothing else' as you are trying to claim.Why do mainline kernel builds have a -<series> suffix?
Each mainline build is named by the base upstream version suffixed with an Ubuntu release name, 2.6.35-maverick. This tells us the upstream version which was built, and additionally which configuration was used to build it. This tells us which release is most compatible with the kernel as built. This does not prevent the kernel being used on other releases, though it is most likely to work correctly on the release it is build for, or earlier ones. The further away from your base kernel release you are the more likely that there will be an incompatible userspace interaction which will prevent them working for you.
In 3 pages, I haven't found anyone that has suggested why you would want to switch to a non-PAE kernel if your CPU supports the extensions. Does anyone have any empirical proof that it adds overhead when you are using less than 4GB's of RAM? PAE adds hardware support for the NX bit which saves the OS from having to emulate it, which comes into play with preventing buffer overflow exploits.

Yes you can just use synpatic to install the generic non-pae kernel.. I just did ..
I also multi-boot way to many versions takes me hours just to update LL to PP plus squeeze and WindozXP. But my controlling grub is installed in my LL and I run Grub-Customizer to help me make grub changes quickly.Code:Linux greg 3.2.0-12-generic #21-Ubuntu SMP Tue Jan 31 18:40:37 UTC 2012 i686 i686 i386 GNU/Linux
Question was your install a regular Ubuntu or Lubuntu 12.04?
My recent Lubuntu 12.04 iso that I dd to my flash drive has the pae kernel too.. I have not installed it yet..
By the way no big performance change obviously. I do have 4GB of RAM but i never use it all anyway. Yes I could run 64-bit and have but see no great gain for me..

lubuntu 12.04 A2 daily build Feb 4 won't boot on IBM Thinkpad T40 "kernel requires pae".
Actually running lubuntu 12.04 Alpha 1 updated to today running O.K.
Nice peppy responsive notebook. I'd think it was the perfect target for lubuntu. Not so.
