Briefly, I have an Athlon MP 2000+ Asus A7M266-D (Dual CPU) system: Here's the dmesg (this may also provide other info on other errors) When I run /sbin/poweroff it also dumps to console that it had one preempt left (I forgot the actual message it outputs). The problem is this: When I run the halt/poweroff program, it powers off the hard disks, and displays the 'Poweroff System' message. If I press the power button, It turns the system off HARD, Ie, i don't see the NIC card's aux power on, and when I try to turn the machine on again it won't until I physically remove all power (turn off powerbar) for a few seconds, then It will let me power it on (or it will power on itself). This did not happen in the 2.4.x kernel, I assume a new ACPI bug? ;-) Shawn. -- Shawn Starr, sh0n.net, Maintainer: -shawn kernel patches: http://xfs.sh0n.net/2.4/ Developer Support Engineer Datawire Communication Networks Inc. 10 Carlson Court, Suite 300 Toronto, ON, M9W 6L2 T: 416.213.2001 ext 179 F: 416.213.2008
