Here are some more details on the panics I see: a. I was seeing them all the time at `shutdown -p', but never with `shutdown -r' (or at any other time, for that matter). b. if I startup with ACPI turned off, I will not see a panic at `shutdown -p'. Of course, that also means that the machine does not really power down by itself. I would have to be present to flip the 'off' switch. c. All of this testing has been done using the 'vr0' ethernet interface, which is on the motherboard that I have. It happens that I wanted to have a second ethernet interface for testing. I added an PCI card with a sis0 ethernet interface, moved the ethernet cable to it, and changed rc.conf to use sis0. Since I switched to using sis0 instead of vr0 for ethernet, I have not seen any panics from doing `shutdown -p' with ACPI turned on. The machine now does power down completely. All of this is on RELENG_5_3, up-to-date as of about 4pm on Saturday. -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu
