Bug Description
With my Amilo M7400 and the recent Precise kernels (at least 3.2.0-[10-12] I think), the system freezes during boot with the Ubuntu logo and colored dots on screen (the dots stop progressing), when I have wistron_btns enabled in /etc/modules. I need wistron_btns on this laptop for the wireless to work, which is why I'd like to have it enabled.
This is unrelated to Bug #926007 which I also just filed: the wistron_btns freeze happens even when I'm using fbdev. (With -intel, the #926007 panic and this freeze take turns in who gets to mess with me.)
From what I've gathered so far, it seems that wistron_btns works fine if I manually modprobe it from my desktop, after booting without it. So that's a workaround at least.
I can kill the freeze with Alt+PrtSc+REISUB. I'll provide any additional info needed, though I don't know how to produce logs when the system is frozen.

Thank you for taking the time to file a bug report on this issue.
However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.
We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.
You can update to the latest development kernel by simply running the following commands in a terminal window:
sudo apt-get update
sudo apt-get upgrade
If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.
If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.
Thank you for your help, we really do appreciate it.
