Is the LSI chipset something you guys have on an add-on card
(something we can put into a reference board) or is hard wired into
your boards?
If its an add on card a pointer to one would be appreciated.

I am also having problems with PCI-E device LSI 1064E on 2.6.24-rc6
kernel. This is running on 8641D processor.
I can see the device, access the config space, but seems access from
device to memory is not working. Same device (same exact hardware)
works
fine for 2.6.15 kernel.

All,
I'm new to this mailing list, but have not had any luck finding
information on this issue.
Please be kind if I break the forum rules on my first post.
We recently tried to upgrade our Freescale CDS 8548 look-alike
module (code name ATCA1000) from the 2.6.11 based BSP to the 2.6.23
based BSP.
The upgrade went fairly smoothly, until we tried using SOME pci-e
devices (some work fine, some don't show up to lspci).
LSI pci-e controllers no longer show up at all!
We see the ixgbe (intel 10G), SiliconImage SATA controller but do
not see LSI devices (Specifically 1068 SAS, FC949-E fibrechannel).
We're guessing it's a resource issue behind the bridge, because the
LSI devices try to allocate 1 - 3M behind the bridge, but we can't
find the bug, or where we would debug such an issue.
The devices seem to "train" correctly, because we have an LED on the
pci-e switch (PLX 8 port pci-e switch), and it's ON indicating pci-e
link between the bridge and the 1068 device).
We're totally at a loss as to why this always worked on the 2.6.11
kernel but doesn?t work on 2.6.23.
Using lspci, the LSI adapters do not show up in the list at all, as
though they are not plugged into the system.
Is there something that needs to be done with respect to PCI-E
devices that is new in the 2.6.23 based BSP that did not need to be
done in the 2.6.11 based kit? For example, are pci resources
allocated by a different piece of code, that may have some issue
allocating resources for the LSI adapters?
Can you tree 2.6.25? There are some fixes in that kernel related to
PCIe support:
[POWERPC] FSL: Rework PCI/PCIe support for 85xx/86xx
However, its odd that lspci doesn't even show the device. Are you
using u-boot? if so what version? and does u-boot see the LSI?
