Urk. You are right. The problem is that id_driver is a wild pointer. It was pointing to an entry in a malloc'ed array that was built to make isadev->id_driver->name work for userconfig. After the exit of userconfig, these tables are freed up, but the uc_devlist stuff still contains a pointer to the original &isa_drvtab[i]; which is long gone...
