Sorry, USB keyboard didn't work in KDL. I've attached a PS/2 one now for future occurrences.
Feel free to close it if it is meaningless as-is.

Had the very same (comment 3) on hrev35738 gcc4h on svn up. Will get the slab_* outputs when I get this KDL again. (bt looks same, so ommiting the picture upload, if not requested otherwise)
Note:
See TracTickets
for help on using tickets.
A stack trace is generally very helpful. In this case also the output of:
