Would timesync cause venti or something else disk I/O related to go completely fubar? It looks like my plan 9 box is now hosed again and will not boot. My hard disk activity LED was almost solid on during this interrupt storm that was going on almost all day yesterday. Not sure if timesync can cause that kind of behavior, and I've no idea why a fresh install with no post-configuration should behave that way. Dave
