No ACPI.

Please raise a report against acpi_bios@kernel-bugs.osdl.org at
bugzilla.kernel.org, thanks.

I believe that just means the machine doesn't support ACPI at all..

Yes; same as me.

Andrew should I report it anyway?

From Alan message I understand that he believes it is a firmware
issue. I tried (without success) to contact DM&P about it asking for a
newer BIOS but nothing yet.

If I could workaround it, it would be nice since it could avoid issues
for users of those devices. I did research on Internet and found a lot
of users having the network adaptor not work and like and those
problems mostly looks like same issue I'm having.

Looking at the BIOS manual on their web site:

ftp://download@ftp.dmp.com.tw/vortex86sx/Vortex86SX_BIOS_Manual.pdf

you can try toggling a few of the options: Try switching OnBoard IDE 
Operate Mode between Legacy Mode and Native Mode. If the kernel and the 
actual device disagree here, that could cause IRQ delivery problems. You 
can also try playing with the "Plug & Play OS" setting.

The machine with me has no "OnBoard IDE Operate Mode" option. "Plug &
Play OS" has been tried with "Yes" and "No".

If the kernel and the actual device disagree, could it  also "break"
the ethernet adaptor? This also doesn't work.

Well, the ethernet adapter would likely be a different problem. Do you 
get any interrupts showing up in /proc/interrupts for either the disk or 
the network adapter?

I guess I did the test with a mangled configuration file and then the
network didn't work. Now I tested it again and it has work fine.

What still fails is the disk. It still doesn't work et all.

I'm sending the /proc/interrupts. It got IRQ 14 for the disk adaptor.

Are there any BIOS SETUP options for enabling/disabling ACPI?

Does any other version of Linux, or any other OS find ACPI support?
does "acpidump" run as root output anything?

I couldn't follow your link to the BIOS manual, but if there
are some docs on this system that could tell us what the
hardware is and if it is supposed to suport ACPI or not,
that would be a clue.

thanks,

So I did. Here goes the dmesg with the debug enabled.
