In HEAD, devd should be firing off rc.resume, but the problem is in the suspend side. When triggered by Fn-F4, there is no way to be sure that rc.suspend is complete before the system halts. zzz (or acpiconf -s3) will complete rc.suspend before actually telling the system to suspend. On the other hand, Fn-F4 immediately starts the suspend sequence. While I believe that it can be set to wait for a specific period before suspending, I don't think that there is any way to assure that anything completes. njl@ or Bruno Ducrot would know more about the details. This has been discussed in the past; probably in acpi@. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
