Hi Pavel,

http://bugzilla.kernel.org/show_bug.cgi?id=5958

do you have the full oops message for me? However it has been a while since I worked with serial line disciplines and the serial subsystem is changing too often, that I lost track. Does the attached patch helps or is the problem another one. Do we need to keep track of the hangup in the serial subsystem?

Regards

Marcel
