I think that the problem is that we have an infinite recursion that is trashing the stack. This is happening in hwpath_to_device() which is called by pdcspath_fetch(). hwpath_to_device tranverses the device tree. It looks like it recurses forever, eventually filling up the stack and trashing stuff. Not yet sure why, nor do I really understand how the device tree iterators work. Perhaps somebody else who understands this better will be able to fix it quickly ;-) randolph _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linux.org/mailman/listinfo/parisc-linux
