Re: IBM HS20 Xen 4.1 and 4.2 Critical Interrupt - Front panel NMI crash

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

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.

Re: IBM HS20 Xen 4.1 and 4.2 Critical Interrupt - Front panel NMI crash

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)
Thanks

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.
