Thank you for your message! I agree that it does not look like a load problem, and that it happens while typing quickly.
Do you know if one has the same problem with a kernel 2.4.x? I have installed also a Mandrake 10 and there everything works properly (both mouse and keyboard) with the 2.4.x kernel. With the 2.6 kernel the mouse tapping doesn't work.
I took a look at the page suggested by Mattia Dongili,
http://www.thorstenhaas.de/toshiba2410/
There 5 methods are suggested to cure the keyboard problem. I tried the last 3 methods, one disablign Xkb, the others using two different ways of suppressing keyboard bouncing while using Xkb (with AccessX and xkbset respectively). None of them seem to work in my case (in fact my notebook is Satellite M30, while the page refers to 2410).
I also tried the method suggested by Marco Kraus (http://www.linuxstuff.de/toshiba-m30/toshiba-m30.htm). He says that one should disable synaptics recognition, forcing PS/2 support. Therefore I removed xfree86-driver-synaptics and configured X to use IMPS/2. Kraus also suggests a correction (not very clear) in one of the Kernel source files. This seems to be already done in the present version of the kernel. Nevertheless all this didn't work.
Unfortunately this problem is pretty annoying.
I hope there are some other ways to try.
Thank you very much
