Dear Cristopher, The model was a Toshiba NB100-10X which i do not have since then. The problem as far as i remember was caused by a faulty interrupt of a laptop battery (some chinese unicode characters appeared in the identifier string, which the driver could not properly handle). Passing the -irqpoll flag worked the problem around.
