I have already. I have them completely locked by vm_mtx now, but that results in some fun lock order reversals. I'm still having problems though. I'm also seeing vm_page corruption on the x86. My patches ar efull of debugging cruft right now though, but I'll try to put up what I have so far tomorrow. Unfortunately, I have meetings until then. :-/ I also have a new KTR tracepoint for trap's that should make things slightly easier for panics like this where we fault in a fault handler. -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
