Hello, KylongMu, Rune!
(Please reply to the thread.)
First I according Clemens Koller' suggestion : remove DMA part ,
but the result is no change.
Okay, sorry if my 'workaround' (let's call it 'cheat') didn't do it for you...
According Clemens Koller's message , I guess mabe the problem is on the
hardware configuration.
So I checked my schematics and
arch/ppc/platforms/85xx/mpc85xx_ads_common.c at line 170 .
The attached file is changed .
After these , Lost interrupt appears on PCI1-Slot1 , but my
PCI1-Slot2 shows no Lost interrupt
the .config file is still without change .
Another new problem is I can't mount it on , I attached the steps
message of new operation.
Please help me check it .
To be honest, I didn't tell you that there are still issues with my
mpc85xx_map_irq() and friends(). I didn't fix the table for my board
yet as the official CR854 demo board has only on PCI slot and I just
didn't care about proper IDSEL-IRQ mapping.
The hardware add-on we design should be compatible to the ADS board (or to
be precise to the default mpc8540_ads behaviour in the kernel) as much
as possible, so there should be no need for a separate platform port.

Yes, but AFAIK it's only 32bit/33MHz PCI and therefore not speedy enough for
the things we want to achieve (100..200Mbyte+/sec).
So, this problem with the PDC has to be fixed... but it will take some time.
Best greets,
Clemens Koller
