I've got an LSI SAS2008 controller (w/ firmware v9) that works
fine in a Linux PC w/ a recent kernel. It does NOT work on my
460EX board. What I find is that the device shows up as every
device on the subordinate bus where it is really located. (see
the dumps below). With the LSI firmware v8 this didn't occur
and it showed up correctly as a single device. I am not sure
how to debug this problem. I've tried disabling the PCI quirks
but it did not make any difference. Any insight or bold visions
are appreciated.
The design details of the minimal configuration is the following.
The PLX is a PCIe switch. I've also tried other more complicated
setups, but they fail in the same way. Everything I've tried
works fine on the PC (cpu->switch->switch->lsi2008, etc).
460EX->PLX8612->LSI2008
Thanks you.
In the logs it is vendor id 0x1000 and it shows up as
every device on bus 83. Note that I disabled the mpt2/fusion
driver b/c otherwise the kernel will crash when it tries to
access one of the devices that doesn't exist.

Ok, I've narrowed the scope of the problem some. I moved forward
to a more recent kernel (2.6.31 to 2.6.36) and that resolved the
problem of the controller showing up as every device on the bus.
However, from 2.6.37 to the current HEAD, I have not been able to
build a kernel to run on the 460EX. I tried 2.6.37, 2.6.38, and
the HEAD and all result in the following kernel panic. I am not
sure how to proceed here. I suppose we can stick with 2.6.36 since
it works, but I'd like to understand what it might take to remedy
this.
Thanks

Smells like somebody changed something with the OF flash code... Josh,
Grant, any idea what's up there ?

Not sure, more information would be helpful.
Ayman, if you do a 'git log v2.6.36.. drivers/mtd/maps/physmap_of.c',
then you'll see a list of commits touching the mtd driver. Would you
be able to do a 'git checkout <sha1-id>' on each of those are report
back on at what point things stop working? Actually, a full bisect
between 2.6.36 and 2.6.37 would be best, but this is a good start if
you're limited on time. Once you find the first commit where it
fails, do a 'git checkout <sha1>~1' to confirm that it is in fact the
commit that causes the breakage.
Can you also post your device tree please?
Thanks,
g.

I can try to find the commit tomorrow. In the interim, i've pasted
the dts below. The board was originally based on the canyonlands, but
we've made some changes, mostly to the pcie. we run the 1-l port in
endpoint mode, we have a chain of plx switches and devices on the 4-l
port. One item that I don't think would matter, but is not too common
is that we are booting these over the pci bus from another PPCs memory.
I only mention this since this failure is during boot, though everything
should by local to the cpu by this time.

Hmmm, considering that there is no device node for NAND in this tree,
something is definitely wrong. The NAND driver should not be getting
probed. If you can do a git bisect on the kernel it will go a long
way to figuring out what is wrong.
I suspect that it is related to merging of_platform_bus_type into the
platform_bus_type. It looks like a device is getting incorrectly
matched to the driver, but I don't know why.
It would also help to add this code to 2.6.38 and send me the log
output:
g.
