Ok, everything is working well, except for one last thing... I load the driver the first time, and it loads correctly. I unload it and reload it and it attempts to attach twice (with the exact same resource values). I unload and reload it and it attempts to load 3 times, unload/reload ... 4 times (you see the pattern). If I load the second module I am working on (exact same type as this module), it tries to re-attach the old module "N" times (depending on the number of previous unload/reloads). I am obviously building up state somewhere in the kernel... how can I get rid of this "state"? -- David Cross | email: crossd@cs.rpi.edu Lab Director | Rm: 308 Lally Hall Rensselaer Polytechnic Institute, | Ph: 518.276.2860 Department of Computer Science | Fax: 518.276.4033 I speak only for myself. | WinNT:Linux::Linux:FreeBSD To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
