When I plug in my BeagleBone to my linux system (it runs Debian sid
and is up to date running linux 3.1.0) I get a crash in syslog.
The full syslog entry is attached as trace.
From the names in the stacktrace it may be to do with the udev rules
that are recommended with for the BeagleBone:-
ACTION=="add", SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_interface", \
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="a6d0", DRIVER=="", \
RUN+="/sbin/modprobe -b ftdi_sio"
ACTION=="add", SUBSYSTEM=="drivers", \
ENV{DEVPATH}=="/bus/usb-serial/drivers/ftdi_sio", \
ATTR{new_id}="0403 a6d0"
ACTION=="add", KERNEL=="ttyUSB*", ATTRS{interface}=="BeagleBone", \
ATTRS{bInterfaceNumber}=="00", SYMLINK+="beaglebone-jtag"
ACTION=="add", KERNEL=="ttyUSB*", ATTRS{interface}=="BeagleBone", \
ATTRS{bInterfaceNumber}=="01", SYMLINK+="beaglebone-serial"
Once this has happened the usb serial module, and ftdi_sio are
impossible to unload.
