Hello,
I have the same error, server is auto rebooted during every boot with
kernel XEN, HS20 with Debian Wheezy and XEN hang on and AMM managment show
same errors described in previous mails. With Debian wheezy wit non-xen
kernel boots correcte, it seems that problems is with xen kernel
Same Server HS20 with Debian Lenny+ XEN 3.2 or Debian Squeeze+XEN
4.0 working perfect
Upgraded to Debian testing and unstable with same results XEN 4.1 and 4.2.
If you need more information, you can ask.
How can be solved this bug?
Thanks

Hello all, Today Xen finally running on IBM blade server machine, try to
add nmi=dom0 and find the Base Board Management Controller on bios

won't eliminate the nmi problem since I still found NMI error interrupt on
my blade server log but xen would ignored and keep running. If any other
found better solution would be great.
Thanks for the 'workaround' info.
We still should find out what exactly generates/causes that NMI with Xen..

Just to add that I also tried the nmi=ignore parameter for Xen, and it
stills hard reboot/resets automatically during the kernel dom0 boot Fabian

Did you the workaround help?
And in regards to finding out exactly what causes it - well there are
logs in the BMC that can point to it the PCI device? Did you check those?
Do they save if there is any device that has PCI SERR on them?
Thanks.

Hello,
We need this server and we have made a downgrade to Debian Squeeze.
I hope in a few day to have another HS20 to make some additional test, I'll
try to get all information that you asked and send
Sorry, one question what is PCI SERR ? Where?
Thanks for all

If you log in the BladeCenter webfrontend you should see logs of
each blade. Some of them are 'User XYZ logged in'. But in some cases
the are more serious ones - such an NMI or PCI SERR. If you could copy-n-paste
them it could help in figuring which PCI device is responsible for causing
the NMI.

Doing a simple Google search on HI_FERR tells me that it is:
http://www.intel.com/content/dam/doc/datasheet/e7525-memory-controller-hub-datasheet.pdf
and that
3.6.14 HI_FERR – Hub Interface First Error Register (D0:F1)
has something in it. The value is 0020 (is that decimal or hex?). If it is
decimal it is then 10100, which is bit 2 and 4:
bit 2:
HI Internal Parity Error Detected. This bit is sticky through reset. System
software clears this bit by writing a ‘1’ to the location.
0 = No Internal Parity error detected.
1 = MCH HI bridge has detected an Internal Parity error. Non-fatal.
and bit 4:
HI Data Parity Error Detected. This bit is sticky through reset. System software
clears this bit by writing a ‘1’ to the location.
0 = No HI data parity error.
1 = MCH has detected a parity error on the data phase of a HI transaction.
But that is unlikely as these are 'non-fatal'. So if this is hex, then it would
be bit 5, which is:
Enhanced Configuration Access Error. This bit is sticky through reset. System
software clears this bit by writing a ‘1’ to the location.
0 = No Enhanced Configuration Access error
1 = A PCI Express* Enhanced Configuration access was mistakenly targeting
the legacy interface. Fatal
That sounds more like it. So we touched a PCIe Enhanced Configuration (MMCONFIG?)
using the legacy interface (cf8?).
Jan, any thoughts? Is there a particular bug-fix we are missing in Xen 4.1 or Xen 4.2
for this? Xen 4.0 seems to work.
Trenta,
When you used Xen 4.0 did you use the same kernel as with Xen 4.1 or Xen 4.2?

Possibly MMCONF just didn't get used on 4.0?
And no, I don't think I recall any possibly relevant change. Even more,
the description above sounds more like an error resulting from device
misbehavior than from software incorrectly doing some access.

Hi,
With Xen 4.0 kernel used was 2.6.32, default kernel Debain 6 (Squeeze)

So if you swap either kernel or hypervisor do you see this? Meaning
if you run with Xen 4.2 + 2.6.32 or Xen 4.0 + current kernel.

Hello,
I have created a bug and added information that you asked, with Debian
7 and xen 4.0 works. It seems that the problema is xen >=4.1is the
problem...
Also tried with citrix xenserver 6.2 same errors in amm, adn we can't
install, server is rebooted automatically.
Bug:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=760563
I hope that this can help
Thanks

So did you try the option Ian suggested there? It is well possible
that newer Xen makes more use of the extended config space.
And if that results in the described error, this _still_ means a
hardware issue, not a software one (for which the use of said
command line option would only be a workaround).

Hi,
Thanks for you answer, I have made some test detailed in
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=760563
It seems that is not a hardware issue, it seems a problems with xen
mmcfg with this hardware. Will be solved? Can I use for a production
environment this workaround?
Thanks

That's a question to the hardware vendor.

I guess so, if you're not requiring any of the functionality needed
extended config space access, like SR-IOV.

Hi,
With xen 4.0 or citrix xenserver 5.6 works perfect, why you say that
is a hardware issue if we don't use xen >4.0 works perfect? Also I
have tried with two differents server with same result, I'm not sure
that is a hardware issue after to do this test on both servers...
Can you give me details about what is mmcfg, I have searched but I
can't find any detailed information.
Thanks

I'm afraid this doesn't rove anything, it could easily be that Xen <=
4.0 simply doesn't tickle the bad hardware behaviour.

Two different servers or two of the same kind? It's not unexpected that
two of the same type of server would have the same firmware/hardware
issues.
I think step one should be to make sure that you have the very latest
firmware (BIOS etc) for the hardware.

AIUI it's an extended mechanism for accessing PCI configuration space.
Xen prior to 4.0 most likely didn't use this method which is why it
works ok.

This sort of argumentation would preclude newer versions from adding
new functionality.

This is an alternative access mechanism to PCI config space, required
(except on AMD systems) to access extended config space, and also
(universally) required to access the config space of devices on PCI
segments other than zero.

Hi,
We have tried with two differents servers but same type (HS20) and
both with latest firmware, bios,... and with same results, no
working.
as you decribed, if mmcfg is a new option added to xen >4.0 this could
be the correct answer for this issue with this hardware. We were
working with xen 3.2 and 4.0 with this hardware without any error or
problem.
Remember that HS20 are IBM blade server, I don't know if this could be
a problem...
What do you think if we work enable mmcfg=0, this could be a correct
solutions and we can work without any problems o incompatibilities?
Thanks

Yes it should work - as you say - it is a blade hardware and it does
not have any SR-IOV functionality, so the MMCONF usage is not needed.
The SR-IOV functionality for blades came much much later.

Jan already answered this further up the thread:
I guess so, if you're not requiring any of the functionality
needed
extended config space access, like SR-IOV.
IOW you should test with this option in your usecases. If it works then
go for it.
You should also report it to your hardware vendor.
Ian.

OK, Thanks for all
We will use with mmcfg=0
Solved and thanks for all !!!
