Hello.

I recently upgraded to 12.10, but I'm stuck on kernel 3.2.0-32. When booting the newest kernel I get only this on my screen:

Loading Linux 3.5.0-17-generic...
Loading initial ramdisk...

And my computer is completely stuck at that point. The only way to make it respond is to forcefully power it off and on again.
I read on this forum that 3.5.0-17 was buggy and I should try 3.5.0-18 from quantal-proposed. The result, however, was exactly the same:

Loading Linux 3.5.0-18-generic...
Loading initial ramdisk...

And stuck again.
Recovery mode on both kernels, though, is working fine.

Is there any way I can make the new kernels boot, or am I stuck on 3.2.0-32 for the time being?
