I don't want to put the user through more debug. For us disabling agp(4) in the kernel config is a viable option here. But I can ask the user= to try a patch probably. I noticed there is no mutex locking in agp_close() as seems customary in the code around am_is_bound et al. But it's probably irrelevant due to Giant l= ock?
