I'm using a Toshiba SD-M1612 and a Liteon LTR12101B. The Toshiba works fine, but the Liteon drive causes problems The Toshiba is secondary master on the standard IDE-controller while the Liteon is primary master on an additional Promise IDE-controller. I've already searched on the web and the archive, but found only information and patches for 4.6 and the 4.7-release info says that this problem has been solved in 4.7. Does anybody know what might be causing this problem? Bye Marc To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
