Let me step back here and reiterate. This panic is occurring in the 'sd' driver. The function xdfs_probe() is part of the 'sd' driver, not mine. sd first calls ddi_get_instance(dip) which returns -1. When xdfs_probe() then calls ddi_get_soft_state(xdfs_ssp, -1) the system panics. This all occurs because my driver has attached to the system and I'm wondering what I've done or not done as the case may be. > You normally call ddi_soft_state_init() in _init() and > ddi_soft_state_zalloc() during attach().
