This is because your system is violating the PCI spec. There is
now an explicit test for this during driver initialization so that
the driver doesn't unexpectedly fail later. I can change the driver
so that it doesn't print out the diagnostic if it would make you
feel better. 8-)
Just out of curiosity, what MB/Chipset are you using?

Thanks for taking care of people with bad hardware...

No, just keep it like that... It is a dev kernel !

This is an ASUS P4S8X MB.
Not sure about the kind of chipset you are looking for, so here
are some details (but full spec are avail at asus web site).

There may be options in your BIOS to disable this "feature". Look
for things like "PCI byte-merging" and/or "PCI read prefetch". I
haven't had access to one of the new SIS based P4 systems yet, so
I don't know how they are setup or exactly how they are violating
the PCI spec. The test will fail either if byte-merging or read
prefetch occurs and perhaps if there is an MTTR covering the memory
mapped region of the chip that is set to write combining mode (I
don't think that the mb() we issue after every memory write helps
in this last case).

I've been looking at the PCI option in the BIOS...
1st part is mapping IRQ to PCI slots...
Then, you have :
PCI/VGA Palette Snoop Disabled
PCI Latency Timer 32
Primary VGA BIOS PCI VGA Card
USB Function Enabled
USB2.0 Function Enabled
Onboard LAN Boot ROM Disabled
Maybe related, the memory config :
SDRAM Configuration By SPD
Chipset clock mode Synchronous
SDRam Command Lead-off time Auto
Graphics Aperture Size 256 MB
AGP Capability 4x Mode
AGP Fast Write Capability Enabled
Video Memory Cache Mode UC
Memory hole at 15M-16M Disabled
PCI 2.1 Support Enabled
Onboard PCI IDE Enable Both
IDE Bus Master Support Enabled
Could it be PCI 2.1 Support ? Don't think because I've restarted
with it disabled, and I still have the same problem...

Paul

No. That shouldn't make a difference.

The messages and the inability to run 2.5 kernels are not related. The
diagnostic prints and the driver falls back to using the "safe" PIO method.

Ok, but it's the only error message I get and the AIX7xxx driver then
fails to initialize.

Can you be just a bit more specific? Actual driver messages are
usually a big help.
--
Justin
other then the memmap error (in my case device 0:10:0 I get the first
three lines of the driver init and then nothing. the machine
completely locks up (driver version on .54 is 6.2.25 but I've
had this same problem since .50)
here is what I get on 2.4.18, the only difference on the first three lines
between this and 2.5.54 is the driver version number

Some things to try:
o Turn on the nmi_watchdog. See the help file in the kernel Documentation
director on how to enable it for your system.
o Compile in the debugging code for the aic7xxx driver and turn on some
debugging options. Use your favorite kernel configuration utility to
enable the debug code and use an aic7xxx command line like:
aic7xxx=verbose.debug:0x12ff

I will try this later

I added this to lilo and it gets a series of messages that quickly scroll
off the screen
it starts with slave alloc 0
then starts the DV process and goes from state 0 to state 1, gives a
couple errors that I couldn't get and then goes into a loop
the looping messages are
sending INQ
timeout while doing DV command 12
command completed status=0x90000
entering ahc_linux_dv_transition, state=1, status=0x14005, cmd->result=0x90000
going from state 1 to state 1
thanks for your help, I was beginning to wonder since nobody had responded
to my previous messages.

I need to see the exact messages. Can you use a serial console to
capture the messages? To avoid unwanted command timeouts, you should
run your serial console at a reasonable speed (115200 or faster).

The problem with the message is that it makes people think PIO vs DMA
(which matters a lot for e.g. IDE), not PIO vs MMIO which is what it
really is, and doesn't matter nearly as much.
