Gee, is that perhaps because FreeBSD keeps breaking the ABI to modules so every vendor that has ever tried to use them has been bitten by the fact that they have to maintain N version for each branch of FreeBSD??? > Are all modules effected, or only those that use certain interfaces? Given that this is a change in splxxx() I suspect that it breaks most modules, but probably not all modules. A quick grep -l spl * | wc vs ls | wc shows 77 out of 100, not exact due to probable false hits on spl, but it gets us the ball park, significant is what is says. -- Rod Grimes - KD7CAX @ CN85sl - (RWG25) rgrimes@gndrsh.dnsmgr.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
