A fix to PCI Express error handling of Unrecoverable Errors went into snv_54. I am interested to know whether you still see the problem without applying the work-around. Let me know, thanks. -- mark dot logan at sun
The bug ID is 6477887: Description There are three issues 1) To be compliant with PCIe v1.1 specification that talks about Role based Error Reporting bit and how to handle Unsupported Request Errors, we should disable UR for any x86 non-RBER enabled leaf device long term. This is part of Baseline Error support of PCI Express. 2) Looking back at s10's pci_pci.c, Master Abort Mode bit (MAM bit) wasn't set for P2P Bridges. Disable that for PCIe2PCI bridges as well. This happens in Baseline Error support of PCI Express. 3) Xorg may fail or scanpci can cause NMIs. This may be occuring due to Completer Abort errors from PCI Express (AER section).
