9-RELEASE works fine. csup to 9-STABLE and make buildworld kernel etc gives a system the hangs during the boot process. There are no error messages during the part boot, and no panic. Last messages before hang are: pcib0: <ACPI Host-PCI bridge> port 0xcf8-0xcff on acpi0 pci0: <ACPI PCI bus> on pcib0 I am stumped about how to diagnose this, and would be _very_ grateful for any suggestions. When it's hung I can't force a break to debugger (BREAK_TO_DEBUGGER) in kern conf: I imagine I'm too early in the boot sequence. - Harry -- Harry Newton

I've sometimes gotten an extra clue from a hang during boot by building with option BUS_DEBUG. Even if you don't suspect the newbus routines as directly being the problem, sometimes you get a bit more info about what was happening at the time of lockup. -- Ian
