I'd like to help someone fix whatever this remaining ata bug is in 4.6 and -stable, but I'm stumped on how to do this. I can break into the debugger, but my only option there to write a core is to "panic" again, but since there's no dump device configured yet... chicken and egg... Is this at all possible? I couldn't find anything in the DDB manpage, nor in a quick google search. Thanks, CS To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
