I upgraded my ac100-10D from 11.10 armel to 12.04 armel and although
everything seems much better now, also lost my trackpad, it just doesn't
work. USB mouse is fine.
My kernel is 3.0.19-2-ac100, here is the result of 'cat
/var/log/kern.log | grep nvec':
Apr 2 20:10:33 lflores-laptop kernel: [ 1.351845] nvec nvec.0: using

It seems the trackpad is not detected, in /sys/devices/virtual/input/
there is
[input1 input2 input3 input4 mice] (without USB mouse connected), but
input[1-4]/name is:
nvec keyboard
nvec sleep button
nvec power button
nvec lid switch button
mice dir only has a dev entry with 13:63
Thx,
Luis Flores

OK, rc.local edited as you proposed.
I will test it and report result (whatever I will find).
Thanks

yes, I also saw this. Could be harmless or the source of the
problems, hard to predict ...
But you can put something like this into your /etc/rc.local:
echo 16384 > /proc/sys/vm/min_free_kbytes
to get rid of the wifi warnings.
A limited emergency pool can also be a reason for lost nvec packages.
