Hi, On a HP ML 110 with this component: > [root@ca1 ~]# lspci > 00:00.0 Host bridge: Intel Corporation E7230/3000/3010 Memory Controller Hub (rev c0) > 00:1c.0 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 1 (rev 01) > 00:1c.4 PCI bridge: Intel Corporation 82801GR/GH/GHM (ICH7 Family) PCI Express Port 5 (rev 01) > 00:1c.5 PCI bridge: Intel Corporation 82801GR/GH/GHM (ICH7 Family) PCI Express Port 6 (rev 01) > 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 01) > 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 01) > 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 01) > 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 01) > 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 01) > 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) > 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) > 00:1f.1 IDE interface: Intel Corporation 82801G (ICH7 Family) IDE Controller (rev 01) > 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01) > 03:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G200e [Pilot] ServerEngines (SEP1) (rev 02) > 04:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express (rev 21) when I push the poweroff button or I run poweroff, the system start the shutdown procedure, but when the system is Off, after 2 or 3 seconds it restart! .. and when it is active, some USB device not work property. Then in order for poweroff machine and do work USB device, i must remove the power cable when the system is shutdown!!.... If I install on this server FC5 all work great. There is a solution to this problem of FC6? I have also install on this HP system F7rc2: with this version of Fedora all work fine, but the poweroff via Button Press not work, I have see witch acpid is not installed by default and there is run a new (for me) process called "hald-addon-acpi: listening on acpi kernel interface /proc/acpi/event" Is this process that it would have to be taken care to poweroff the system? why do not do it? Thank for your reply. -- Dario Lesca <d.lesca@xxxxxxxxxx>
