Hi again,
FWIW, I've rebuilt/backported the 3.2.6-1 kernel from testing for/to
stable (had to revert some changes in the python-based parts of the
Debian kernel build system to make them work with python 2.6) and we
can no longer reproduce the problem.
Cheers,
Rene

Hi Jonathan,
I can reproduce the kernel trace trying to access two FTDI devices
from the same (custom) application. I'm guessing the concurrent access
to the respective USB driver is the actual problem though. This leaves
the driver in a state where communication over the serial link is no
longer
