Hello,
I got this machine working booting it with "irqpoll" parameter however
it drops the performance a lot and I'd like to try to fix the root
problem of it.
Without 'irqpoll' the disk and network adaptor doesn't work.
Thanks in advance for any help,

That implies the IRQ routing is failing which usually but not always
means the tables in the firmware are wrong. The first step would probably
be to dump all the relevant PCI register space and the ACPI tables and
compare them with the IRQ routing documentation for the chipset.
Actually no - thats step 2, step 1 is asking the vendor if there is
updated firmware to fix IRQ delivery problems

No ACPI.

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.

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.

What kernel revision do you are using?
We are using a Vortex86DX here and it works as expected. But I do not know the
differences in the SoCs of Vortex86SX and Vortex86DX (okay, SX lacks the
floating point unit). Find our dmesg output attached. Maybe it could help.

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.

I'll take a look on the dmesg output and see if I see something interesting :-)

This is the same collision I have. Another interesting issue is that
your disk is using the USB bus while mine uses IT821x.
Is your network working? mine does not (inside of Linux but does for
tftp booting).

Yes, our system starts from a fixed soldered USB based disk.

Based on a "RDC R6040 Fast Ethernet Adapter" and the kernel states:
[...]
r6040: RDC R6040 NAPI net driver,version 0.24 (08Jul2009)
[...]
Runs with NFS and without any 'irqpoll' trick. (here the modul:

Our kernel states:
CPU: Vortex86 SoC 05/02 stepping 02
Your kernel states:
CPU: Cyrix Cx486SLC
BTW: Try to enable the DEBUG macro in "arch/x86/include/asm/pci_x86.h" and
boot again this kernel. On earlier kernels this increases the verbosity of
the kernel when it tries to detect the IRQ routing.

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.

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