I wasn't able to boot the Ubuntu daily live image due to bug #1251816,
but I did try installing the Raring kernel (3.8.0-34) on my work's Dell
Inspiron 2650 running Lubuntu 12.04. Booting the 3.8 kernel, the
keyboard trackpad worked every time! I probably rebooted it about 15
times. As far as I
jhansonxi, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com

Title:
Dell Inspiron 2650 (bios A13): keyboard and touchpad fail randomly
--
There is something odd about the point of failures here. This is snippet
of debugging on keyboard+mouse failure case:
[1.361515] i8042: [2] d3 - i8042 (command)
[1.362154] i8042: [2] a5 - i8042 (parameter)
[1.362545] i8042: [2] a5 - i8042 (aux_test_irq, aux)
[1.362560] i8042: [2]
As per my comment on bug #555169
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-keyboard/+bug/555169/comments/50
acpi=off does solve the problem but obviously breaks soft power-off,
sensors, and other things.

Ok, the most common quirks don't make any difference. Can you also test with:
i8042.noloop
i8042.nopnp

Please ignore my previous comment #10, you can test noaux but it should
always keep your touchpad disabled.

Looking at i8042 code, I noticed that Can't read CTR while
initializing i8042 failure happens very early on initialization, so I
expect the noloop/nopnp options to also not making any difference, and
the only option which could change things was i8042.reset but it didn't
as you tested.
Perhaps
I repeated each until it succeeded:
i8042.reset: 1 success/7 failures
i8042.nomux: 1 success/5 failures
i8042.notimeout: 1 success/5 failures
These tests were performed from a power-off condition.
