Hi Marek,

Well you do realize that this addition changes the timing of the code and also generates writes on the AXI bus, right? I would be much fonder of your testing if you did it with a pristine code and monitored the number of successful cases with plain logging of the serial console and a grep. This should be easy and would avoid the problems with modified code.
Ok, so with the debug patch applied I let it running overnight and it ran 39k+ times without PCI linkup failures.
I agree with your comments and now I am doing as you suggested:
Running top of tree u-boot-imx with only Tim's patch applied.
Then I do:
sudo minicom | tee pci.txt to collect the logs.
After one hour of testing:
/tmp$ cat pci.txt | grep CPU | wc -l 2251
/tmp$ cat pci.txt | grep Bridge | wc -l 2251
Could you help testing the kernel patch?
