The fatal problem is probably in poor handling >of SCSI errors. It seems conceivable that certain types of failures that require a recalibrate, or certain types of SCSI devices (like CDROM drives) that need to spin up first could trigger an unnecessary timeout with it set to only 2 seconds. It should probably be increased to at least 10 seconds, but I'll defer to whatever Justin thinks is needed. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
