Hmm, I don't know much about IRQ issues.

I'd start by applying the header quirk patch above, then comparing the
complete console log (boot with "ignore_loglevel") from 2.6.32 and

Thanks Bjorn.
1) If I understand it right this patch only removes the "pci
0000:00:00.0: ignoring class 0x0b2000 (doesn't
match header type 01)" message , don't care about it , had it before .
2) regarding the comparing of printouts:

Hi,
I have a similar problem here on a P4080 based board with the same 3.8 Kernel
from freescale git. Does your system panic (maybe due to a machine check
exception)? If yes could it be the first read from the PCI device?

Hi Johannes
no panic just reboot.
it is not the first read, it takes few minutes of work with pcie to reboot.

>From comparison of pci printout from the two kernel ,
beside the EDAC errors I noticed other strange differences:
In 3.8.13 I got BAR 7 and BAR 8:

It also affects how the PCI core handles the device. But as you said,
if you had the message before, it's probably not the cause of the
current problem.

Can you post the complete logs somewhere, maybe in a bugzilla or similar?
Where are the "PCIE ERR_CAP_STAT" and similar messages from? My quick
grep didn't find them.

PCIE ERR_CAP_STAT is coming from:
drivers/edac/mpc85xx_edac.c
>>Can you post the complete logs somewhere, maybe in a bugzilla or similar?
cant I post here??
Thanks for your time

Did this problem ever get resolved? Is there anything we need to look at?

I compared the configuration hexdump of my pci controller and pci device
(FPGA) on old kernel(working 2.6.32) and new (3.8.13) and the only
difference was on the controller configuration on the memory base at Type 1
configuration header registers
.
what does it mean and could it be the trigger for my problem ?
Thanks a lot.
Leonid

Finally I found the problem causing the sudden system reset :
our setup :
P2020<====>PCI Bridge <=====> FPGA
The reset occurs when we allocating skb and giving the Fpga dma addr of
skb->data of this skb and when the FPGA tries to reach this address we are
having a hardware reset.
To fixed it we used GFP_DMA flag on skb allocations.
If you can explain me few thinks I will be more then happy :
1) how come we managed to work in 2.6.32 kernel without this flag.
2) Ok gave you a bad dma address why reset the system without any warning.
Thanks for your time and support

Maybe you got lucky, allocation patterns changed, etc?

If you write to random addresses arbitrary things can happen.
