Error Logs 5-49
5.4.5 Page Table Entry Invalid Error
Step 6
This error is almost always a software problem. However, if the software is known
to be good and the hardware is suspected, swap the IOD.
5.4.6 PCI Master Abort
Step 7
Master aborts normally occur when the operating system is sizing the PCI bus.
However, if the master abort occurs after the system is booted, read PCI_ERR1 and
determine which PCI device should have responded to this PCI address. Replace
this device.
5.4.7 PCI System Error
Step 8
For this error to occur a PCI device asserted SERR. Read the error registers in all
the PCI devices to determine which device. The PCI device that set SERR should
have information logged in its error registers that should indicate a device.
5.4.8 PCI Parity Error
Step 9
Read PCI_ERR1 and determine which PCI device normally uses that PCI address
space. Replace that device. Also, read the error registers in all the PCI devices to
determine which device was driving the PCI bus when the parity error occurred.
