Hi, I've random hangs like this in the same place on different hardware (Wyse S30, the newer 902114-02L model, with an AMD CS5536 southbridge). I never really figured that out, but I was able to get a little more info during these early stages of boot by, in boot -c, enabling 'verbose', and fiddling with some of the pcibios(4) flags before booting. 'change pcibios' and then setting flags to 0x0030 may be a good idea, as long as you have a convenient way to capture the output (like a serial console set up in /etc/boot.conf). Maybe you'd notice differences between a failed/successful startup. Although, if the crash is happening at some later stage, I guess this wouldn't help. You could maybe try pcibios flags 0x0031, 0x0034, 0x0038, disabling things like acpi, or maybe disabling pchb just to see what happens. Regards, -- Steven Chamberlain [email protected]
