Hi, I have a Compaq evo n160 running FreeBSD biocandy 5.2-RC FreeBSD 5.2-RC #10: Mon Dec 8 19:08:38 CET 2003 The machine fails (and always has) to boot with acpi enabled (locks up when mounting /), however, I managed to find out that booting with the following option debug.acpi.disable="pci" in /boot/loader.conf made the machine boot correctly and acpi related functions such as battry monitoring worked just fine. But, and a huge but, no pci devices are detected during boot (maybe quite obvious because of that debug option) All pci-devices works perfectly with acpi disabled. Now, is there any chance to make freebsd use acpi and the "normal" pci-bus driver at the same time, overriding the acpi pci-bus implementation? I believe linux has a kernel option called pci=noacpi (atleast acording to google), which does this. With acpi enabled scanpci reports all the pci devices, but pciconf -l doesn't return anything. With acpi disabled, scanpci reports all pci devices, pciconf -l reports all devices. dmesg output with acpi enabled http://shapeshifter.se/~fredde/tmp/dmesg.acpi.enabled dmesg out with acpi disabled http://shapeshifter.se/~fredde/tmp/dmesg.acpi.disabled Any, and I mean any, help on this will be very appreciated. Thanks, Fredrik
