[-- Attachment #1 --] Modification of time out values for FreeBSD-2.2.1 & FreeBSD 3.0-970522-SNAP During playing around with my removable media daemon I had this experience that a number of time outs were a bit on the short side: scsi_start_unit scsi_stop_unit Spin down takes approximately 15 seconds on the JAZ drive. When you send the drive a command during the spin down, it locks up and needs to be switched on and off to restore proper behaviour. This solution has been found somewhere in the archives for Linux. Another one is the recognition of the tape drives. Can't remember what I exactly did to that one, but upon recognition of an old Archive Viper with a tape inserted it takes about 40 seconds to get online. FreeBSD in the meantime decides that it needs to pop round the errors departement and go read through those message, aloud. I will post this one as soon as I get that one here. (Don't you love free OS's?)
