On Page 333 I read:
------------------------------
12.10.1 GART Table Walk Error Reporting
--- 8<
MC4_CTL[10] bit is set. AMD also recommends adding a setup option to the
BIOS setup menu. The
following should be displayed in the setup option:
Gart Table Walk Error MC reporting: Disabled/Enabled.
The default setting is disabled. The device driver developer may enable
this function for
implementation and testing purposes. Also, a help message should be
added with this setup option.
An example of the help message is:
This option should remain disabled for normal operation.
-----------------------------------
On Tyan (Opteron) Boards there is an Bios Option
for Disable/Enable
Debugging for Kernel/Driver developing.
And something like "Gart Table ECC reporting/logging".
Maybe eServer has something like that and can help.
