Problem in touchpad after suspend/resume

[Marcos Paulo de Souza]

Hi Zoltan,

I tried to disable nouveau here (by compiling a new kernel and disabling 
all nouveau options), and it gave me a lot of warnings again in ACPI. 
You can take a look at the dmesg here:
https://paste.fedoraproject.org/229610/51495143/

I tried to disable intel grafic driver (i915, by removing the 
compilation of the driver in menuconfig), by the login screen didn't 
started.

I also tried to blacklist nouveau, or to change the order of loading 
these modules, but I didn't figured out how to do it.

Do you have some more points to give me to fix this annoying problem?

Thanks in advance for all your help!
