If these updates are like the ones when I used it, they included the
"previous kernel" option in the bootloader. Just make sure you have the
bootloader option to "ask" enabled, and you should see the whole, endless
list of all kernels ever installed on that machine.
Hope this helps, but I agree with Lee, it sounds unlikely to be the kernel.
PS: But isn't 10.04 out of support, therefore without updates? IIRC, the
stopping of that support is what prompted me to abandon Ubuntu (since I did
not like 12.04 GUI)
