(e.g. The infamous fxp and ncr combo.) and regardless, attempt executing the script that is provided and note whether or not you can reproduce the panic in sbdrop()? If so, a backtrace and a `print *sb' would be helpful, certainly. It looks as though some mbufs are literally being `zapped' off of sb_mb while sb_cc and sb_mbcnt are still greater than zero. Either that, or something's not adjusting sb_cc and/or sb_mbcnt under the proper spl which may lead to an interrupt eventually leading to the sbdrop with an sb_cc and sb_mb that just don't go together. -- Bosko Milekic Email: bmilekic@dsuper.net WWW: http://pages.infinit.net/bmilekic/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
