I don't feel like getting close the root of the problem yet but maybe the attached output helps marcel or someone else to see clearer. I can't pretend that the reset in the attached log is not beeing sent from a user-application but i felt like the oops is worth posting. Kernel used is 2.6.8.1 but i know that the thing happens also with 2.6.17.6.
