It is reproduceable. And contrary to the original boot problem I get excactly the same panic when turning off one SDRAM chip. But the panic is gone if I use a kernel without my rlswitch driver. Now ukphy gets connected to all 6 PHY mappings. Can't imagine at which place rlswitch could have corrupted memory, but maybe it happens because of refusing multiple attachment. -- B.Walter http://www.bwct.de http://www.fizon.de bernd@bwct.de info@bwct.de support@fizon.de
