You're getting the base transfer speed for the bus confused with the actual negotiated transfer speed. 3.3MB/sec is async narrow SCSI, which is the baseline transfer speed for most SCSI controllers. The negotiated transfer speed is printed out when the device probes, and by camcontrol negotiate. > FreeBSD 5.0-CURRENT #18: Fri Aug 10 16:51:25 CDT 2001 [cvsupped about 4am CST today] Tyan S1696-DLUA Mobo / 512M / Two > Pentium-II/333's > > See the full dmesg output in the -current thread I'm about to post concerning ACPI tables not being found, boot_verbose was set. > > The SCSI timeouts have been "normal" here for a couple/few years. Everything comes up fine once it sorts itself out.
