Hello everybody!
I have upgraded from 2.6.15 to 2.6.22 with a mpc866 processor. I haven't
got any idea what is happening in the system, but I got a kernel panic. The
direction of the kernel panic points to the "get_index( )" call into
"prio_tree_insert( )".
I don't think the problem is caused by the uart cpm, but it's also a
possibility.
Here is the console message:

Does anyone know what the problem could be?
