some rt-preempt help if possible.

[Lars Segerlund]

 Hi Everyone,

 The linux cnc is trying to port their software to rt preempt, however
there is a patched version for emc 2.4 that works ok, and when these
patches are brought to emc 2.5 it hangs on startup.

 Aparently it's a mutex that hangs.

 Now any help or pointers would be appreciated, particulary on how to
debug a mutex hang ....

 Roughly the same code runs ok in the old version, and most people on
the linuxcnc list are only familiar with RTLinux and RTAI. Any help
appreciated, since the code is still 'wet', so this is a small call
for help is someone feels like it.

 If it's of topic, or not interesting please ignore.
