I don't know, but I can try. The only problem is that udev has some restrictions on the kernel version. :-( > I did find dmesg logs at > https://bugs.launchpad.net/ubuntu/+source/linux/+bug/343675 (2.6.28) and > https://bugs.launchpad.net/ubuntu/+source/linux/+bug/446911 (2.6.31), which > suggests that linux booted with ACPI enabled on *some* Clevo M5X0JE systems. As per the previous bug, the only version of Linux that I got and that worked before was 2.6.24 and I don't quite remember if I needed acpi=off or not, but I can try it again, of course, and let you know. > I assume Windows still boots on this system (to make sure this isn't > hardware that broke and prevents both Windows and Linux from booting). No the hardware doesn't appear to be broken. And yes, Windows works fine (from the little about Windows that I know). I chose to keep it here, as that's what my mother used to use (but she tells me that she would prefer to switch). Anything works well in Windows and I can try to boot with some logging enabled, if I happen to know where debug messages are sent/put once Windows boots. > Based on your debug output, I think the hang happens when we do an outb() to > I/O port 0x142e to enable ACPI mode. Do you have any CardBus or other devices > you could remove, to make sure it's not device-related? While the notebook has a cardbus bay, it is not in use right now. The only things that are plugged in right now is the power cord and the ethernet cable. I don't have a null cable here to use a serial console or something... I can try to see if a network console works, but I guess that a PCI card would be sort of a chicken-and-egg problem, wouldn't it? Just as a side comment, do these PCI and ACPI problems always go hand in hand? I will try to do a binary search with Linux versions to see if there is any one that can work without acpi=off being passed.
