Fwd: PCIE device errors after linux kernel upgrade

[Leon Ravich]

Hi all ,
I am trying to upgrade ours embedded device (freescale powerPC P2020 cpu)
linux kernel  , till now we used 2.6.32 I am trying to upgrade to 3.8.13 .
I took the source from freescale git:
git://git.freescale.com/ppc/sdk/linux.git

on our embedded device we have an FPGA connected through PCIE .

on each boot we loading the rbf design to the FPGA and the rescan pci bus to let
kernel detect it .

during the rescan I getting error messages:
 genirq: Setting trigger mode 0 for irq 27 failed

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

There's a recent patch related to this:

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
3.8.13.

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?

[Leon Ravich]

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

Ah, OK. Unfortunately I can't really help you then.

Have you looked up the error values from the EDAC driver?

If it's just a reboot without panic, could there be a watchdog resetting the
board?

You may need to check the error code in EDAC driver as Johannes suggested.

Is this still a problem, or have you found a solution in the meantime?

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.

>> 2) regarding the comparing of printouts:

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.

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