Touchpad hang on resume Nevada B119

Hi All,

So the MSI touchpad would not work after resume on B119.

They fixed the issue in B120, problem is B120 would not even suspend, just sit and hange on HD.

I've done a clean B119 install and taken the three 8042 files from /kernel/drv off B120.

No more touchpad issues.

CPU 1 is still pulling 100% busy after resume, but we know it's an ACPI problem, so maybe we can get a fix.

As I mentioned before, after putting the latest BIOS onto the Acer One 10", the problems with ACPI lid taking 30 seconds to suspend the netbook has gone away.

I have B119 with Evolution 2.27.5 and Firefox 3.5.1, it's a pretty cool system.

MSI Wind, fixing the touchpad after resume

Hi All,

 So I went back to B104 on the MSI Wind, just could not really get suspend / resume working on B107.

 Suspend / resume works fine, the touchpad does not work after resume.

If I do this:

modinfo | grep mouse8042
grab the index
modunload -i <index>
modload /kernel/driver/mouse8042

Touchpad comes back on again

So I later found out you really don't have to do the modload, something, is doing it.

Randy F. gave me this:

MODID=`modinfo | grep mouse8042 | awk '{print $1}'`
modunload -i $MODID

I've just put it in a script in /usr/bin, I'll have to find a way to activate it after resume.
