Do a "cvs diff" by date of the Developer's pre-release 1 for the driver and the code areas ou are interested in, and the changes causing the problem will just display (along with other changes, sorry). The easiest approach is usually a bsearch of the code, which is less than 9 compiles to find the day of the change out of a year and a quarter. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
