I saw it with r241541 and not with my previous kernel (strings says it was r238937; July 31). So not a very narrow range for me. The major changes in ZFS in that interval I say in a glance at the log were the TRIM and the tasting-for-root-pool. But I don't have any reason to suspect them other than "hey, these are high-profile". -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
