Hi, I don't know what the difference between the two is. It looks as if "net_bh()" calls devtint ( and i guess doing mark_bh(NET_BH) calls net_bh() ) . My driver calls dev_tint again and again due to heavy traffic and as a result the kernel crashes with the error: "release:kernel stack corruption".
     However when I replace that call with a mark_bh(NET_BH)  then my kernel doesn't crash.
If someone could shed some light as to what the difference between the two is that would be great. Thanks Jaspreet Singh
