I don't think that any of the changes between 6.2.35 and 6.2.36 will
make a difference for you, but you could try upgrading.  The source
files are here:

The console output you've provided makes me think that interrupts are
not working correctly in your system.

Tried those already on both 2.4.21/22 and 2.6.0-test1,2,3.
While the 2.4 driver compiles and works fine the 2.5 sources does not
play nice with 2.6.0-test* kernel.I had to change the includes to blkdev
in the source and then there was few compile warnings.I can try to
provide the exact ones, unless there's a driver that applies to
2.6-test* cleanly.Once i had it compiled the kernel would just panic.

Is this due to my mainboard (nforce2),cpu,ACPI,devfs,sysfs...or all
these together?

I tried swapping the SCSI controller card in various PCI slots,used new
and original working cables,changed the BIOS IRQ's...etc

I start running of ideas here, is there other options to fully debug the
problem? What else can i try? I would appreciate any pointers.

I would like to get things working with 2.6.0 kernels...right now only
aic7xxx_old is somehow working but that's not the solution to the
problem.

NForce2 + ACPI IRQ routing is a work in progress. Try turning off ACPI 
for the time being and see if it helps.

Thanks,

Thanks Rahul, i'll try that.Are acpi=off and pci=noacpi the same options?
what about APIC, should i also use noapic option upon booting the kernel
(APIC is compiled in)?

I've tried all these options...regardless of ACPI being enabled or
disabled the driver still does not see the SCSI drive, both of my cdroms
are seen though.

Justin, I would be willing to test the 6.2.36 aic7xxx driver or variant
of if it was made available for 2.6.0-test3 kernel.

What else i could try? Any other suggestions would be welcome.

It will be a little while before I can get my own distributions up
and running in the 2.6 stream.  I hope to start looking at this next
week.

Hi Justin,

After some more testing i have good news to report.
I am currently running kernel 2.6.0-test4 with aic7xxx driver.

The solution to my earlier problem was in SCSI-Select Utility under
Advanced Settings tab.I have never changed any options under the
AHA-2940U2W bios 2.57.2 but this time i've changed BIOS Support for
Int 13 Extensions from Enabled (default) to Disabled.That made all the
difference when the adapter is probed.

I have a question related to this setting, will this affect anything
when set to Disabled? Perhaps there's something in the driver that
prevents the Int 13 extention from functioning properly?

I can provide .config,dmesg output or verbose messages if needed.

Thank you for helping thus far.

Regards,

Paul

Justin,

I have a nice oops from the
http://people.freebsd.org/~gibbs/linux/SRC/aic79xx-linux-2.5-20030603-tar.gz driver on 2.6.0-test3.

I took few snaps which show the scsi controller scan process and the
oops from kernel, they are at:
http://www.blazebox.homeip.net:81/diffie/images/linux-2.6.0-test2/2.6.36/
