> Hdlr: 00151743 HI Fatal Error, HI_FERR/NERR Value= 0020 > 27 I Blade_09 09/08/13 13:25:17 0x806f0013 Chassis, (NMI State) diagnostic > interrupt > 28 E Blade_09 09/08/13 13:25:12 0x10000002 SMI Hdlr: 00151743 HI Fatal > Error, HI_FERR/NERR Value= 0020 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 â 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 â1â 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 â1â 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 â1â 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? _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
