Woah. COM_LOCK is a special case due to sio/cy using fast interrupt handlers, and if digi is using a fast interrupt handler, then it needs to be a spin mutex, not a regular mutex. Also, mutexes should be on all the time, not just #ifdef SMP. Note that COM_LOCK is always defined now. -- 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 cvs-all" in the body of the message
