The system also is not restarting correctly when i have inserted the
stick.
When i press the restart icon from the login screen, the screen goes
black and the cursor is blinking.

I then have to press ctrl alt del. to restart it, and during this
restart the screen continues to be black.

according to twinmos the stick is supposed to work with kernel 2.4 and
above... thats why i bought it.

What does the acpi do?

And what is the correct way to mount this stick?

Thanx
