Is there a method or callback in FreeBSD where a driver can=20 be notified that it has caused a kernel panic in order to=20 generate a dump of internal hardware state information? I've written a sysctl call for manual intervention and can handle some "expected" hardware events completely in the driver but I don't know of a way to get control again in cases where the=20 driver wasn't expecting a failure.
