Minor correction. Suspend/resume was around in late 3 and 4, though the Nomad code in 3 was a bit unstable. It worked well in 4, but was dependent on APM which was already being replaced by ACPI. By the time 5.2 was actually released, many systems were being shipped without APM, so could not run FreeBSD. (APM was fairly optional, but ACPI systems really need ACPI support.) ACPI was one of several things that forced 5.0 to be released even though RE and everyone running current knew it had big problems. It i also why 5.0 and 5.1 were clearly marked as "development" releases not for production. I really hope to never see a release as ugly as 5. 9.0 may have issues as did 7.0 and 8.0, but for most, it works quite well. I m happily running it on a couple of systems. --=20 R.
