[rtl] kernel crashes with RT-Linux
Dear All,
for a few days now I do have some trouble running my RTL daq modules and the GUI
frontend (called khidaq). All I get regarding the crash is the following output
to the syslogd out-file. The system seems to be stable still after the oops,
just my app doesn't work any more. I don't know wether it's the app itself, my
RTL modules, the standard RTL modules or something else.
So can someone explain what this trace down there means ?
Where do I get information regarding these messages, how can I learn to
understand them ?
