Hey, we're getting somewhere. It works, in that it stops the panic. I get the "ed0: unloaded" message, and the machine doesn't panic, but there are still some problems. It seems that device_delete_child is failing (I forgot to print the return code, but it is not zero), and reinserting the card results in "ed0 already exists, using next available unit number", and then the dreaded "driver allocation failed" (presumably the resources have not been freed). Putting in a different kind of card ends up with two children, so it seems that the only part of the delete actually happens. -- Christopher Masto Senior Network Monkey NetMonger Communications chris@netmonger.net info@netmonger.net http://www.netmonger.net Free yourself, free your machine, free the daemon -- http://www.freebsd.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
