Btw, have a quick search, there are several other drivers that uses tx lock in the tx NAPI.
tx NAPI is not the issue. The issue is that write_msg() (in netconsole.c) calls this polling logic with the target_list_lock held. Are those other drivers called by netconsole? If not, then this is unique to virtio-net. -- Steve
