Description Sage Grigull 2008-03-13 01:36:25 UTC 
Description of problem:
ACPI issues in xen and nonxen kernels on IBM x3400

Version-Release number of selected component (if applicable):
2.6.18-53.1.14.el5 on x3450  and  2.6.18-53.1.13.el5xen  on X3400

How reproducible:


Steps to Reproduce:
1. boot system with recent RHEL5 kernel (older kernels were not available)
2.
3.
  
Actual results:
on Xen kernel:
ACPI Error (exregion-0165): Could not map memory at 00000000FEC80000, size 100
[20060707]
ACPI Exception (evregion-0424): AE_NO_MEMORY, Returned by Handler for
[SystemMemory] [20060707]
ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0._CRS] (Node
c7532590), AE_NO_MEMORY
ACPI Error (uteval-0212): Method execution failed [\_SB_.PCI0._CRS] (Node
c7532590), AE_NO_MEMORY

and on both:
PCI: Bridge: 0000:02:00.0
  IO window: disabled.
  MEM window: disabled.
  PREFETCH window: disabled.
for many devices

Expected results:
No ACPI error on xen
IO and memory windows not disabled

Additional info:
Dmesg grabbed from customer production tickets.  No 'xen dmesg available.
This platform is apparently certified https://hardware.redhat.com/show.cgi?id=235161

Comment 3 Prarit Bhargava 2008-03-24 17:47:43 UTC 
Ed, do we have an IBM x3400 in Westford?
Comment 4 Ed Pollard 2008-03-24 18:04:50 UTC 
Prarit,
 We don't. I might be able to get someone at IBM to do some specific tests for
us at IBM if that would be helpful.
Comment 5 Prarit Bhargava 2008-03-24 18:05:46 UTC 
Marco, 

PCI: Bridge: 0000:02:00.0
  IO window: disabled.
  MEM window: disabled.
  PREFETCH window: disabled.

This isn't a bug/error warning.  It is informational only.  The kernel does not
see any devices behind this bridge and disables the various windows on the bridge.

ACPI Error (exregion-0165): Could not map memory at 00000000FEC80000, size 100
[20060707]
ACPI Exception (evregion-0424): AE_NO_MEMORY, Returned by Handler for
[SystemMemory] [20060707]
ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0._CRS] (Node
c7532590), AE_NO_MEMORY
ACPI Error (uteval-0212): Method execution failed [\_SB_.PCI0._CRS] (Node
c7532590), AE_NO_MEMORY

Also, ACPI may attempt to access physical HW from dom0 which results in these
types of warnings from dom0.  They are also seen IIRC, when ACPI is queried for
CPU information.

ie) this may be NOTABUG.

Are you actually seeing a system failure?

Comment 7 Sage Grigull 2008-04-15 21:52:29 UTC 
Prarit,
the Xen based system had issues provisioning guests.

Ill check with Mark Huth when he gets back for the particulars.
