Thank you: over the next few days, I am planning to attempt a BIOS
upgrade and enter a PR with an ACPI dump (I'll "man" for how to do
such dumps but if anybody has a specific recommendation, please let me
Another thing about ACPI in NetBSD that bothers me: "halt -p" not
always powers off a computer.
I *think* I didn't forget the `-p' option to `halt' last night --
still, the machine was halted without switching off.
This is not unusual for this laptop -- OpenSolaris *never* was able to
power it off (with "poweroff" command).
But this is also not unusual for NetBSD: I have an about one-year-old
desktop with four disk BIOS partitions divided between FreeBSD and
NetBSD, both of the i386 and amd64 varieties.
FreeBSD will never fail to power off that system on `halt -p'.
NetBSD (5.0.1) will sometimes do it, sometimes not: while not totally
deterministic, the chances to be powered off are close to 1 when `halt
-p' is issued on the console, and 0 when the command is entered via an
xterm (displayed on another system).
