Feng, Stefan
Can I do anything else to help you identify the problem ?
Thanks.

Can you turn on the additional debug information. That will give a better Clue as to what part is hanging.
I've enabled debugging in drivers/pci/pci.c. I'm seeing an infinite flow of messages
PCI: Bus Dev VenId DevId Class Int PCI Scan: Found Bus 0, Device 6, Function 0 PCI Scan: Found Bus 1, Device 6, Function 0 ... PCI Scan: Found Bus 255, Device 6, Function 0 PCI Scan: Found Bus 0, Device 6, Function 0 PCI Scan: Found Bus 1, Device 6, Function 0 ...

Hi,
I'm running latest u-boot on 1GHz Canyonlands board and have trouble using 64-bit transparent PCI-PCI PLX 6254 bridge. With PLX evaluation board plugged into Canyonlands PCI slot u-boot hangs. With PCI support disabled u-boot works fine. The PLX board is OK, it was recognized by both u-boot and kernel on Freescale MPC8536DS board. On Canyonlands linux-2.6.32 silently resets the board when PLX is plugged in. Any ideas what could be wrong in u-boot ? I'll post a separate question to linuxppc-dev.

Thanks a lot.
