There's a comment in the code that explains it: /* * XXX We unwisely assume that the detach code won't run while the * XXX the attach code is attaching. Someone should put some * XXX interlock code. This can happen if probe/attach takes a while * XXX and the user ejects the card, which causes the detach * XXX function to be called. */ strncpy(desc->name, device_get_nameunit(child), sizeof(desc->name)); I guess allocate_driver() could call device_get_children on 'pccarddev' and check if 'child' is among the list. That would cover most cases of the device going away during the call to device_probe_and_attach().
