12.04 doesn't boot up after kernel update

Question

I updated from 3.2.0-35 to 3.4 and now it just boots to a black screen after the BIOS. I have to press shift to bring up GRUB and go back to 3.2.0-35.

Any idea how I can get 3.4 to work? If not, how do I remove 3.4?

Also, did I download the right one? The file name says it's for AMD64, but Synaptic is saying it's for 32bit. What's up with that?

This question should instead be filed as a bug report, and as such is off-topic, thanks! Instructions on filing a bug report are here. — Jorge Castro, Jan 05 '13 at 20:39
@JorgeCastro I don't agree with closing it for this reason. The 3.4 kernel not working is a bug, yes, but the "how to revert to 3.2 permanently part" isn't. — gertvdijk, Jan 06 '13 at 00:03
How did you install this kernel? Did you use packages or did you compile it from source? — gertvdijk, Jan 06 '13 at 00:04
I got the ppa from http://kernel.ubuntu.com/~kernel-ppa/mainline/ — teslasmoustache, Jan 07 '13 at 23:00

You can remove 3.4 kernel via Synaptic. (+ info if someone hasn't it)

Install Synaptic with Ubuntu software center
Open Synaptic and press Ctrl + f
Write "linux image" without quotes and press enter
Look for something like linux-image-3.4-x-generic
Press right mouse button on it and select remove
Press "Apply changes" on the toolbar

That's what I thought. I didn't know if it would cause any problems. – teslasmoustache Jan 05 '13 at 21:04
