FYI - pci_mmcfg_init kernel error after upgrading to 5.6
...ne is a G7. After the
upgrade and the reboot to the 2.6.18-238.9.1.el5 kernel, both servers
displayed the following error at boot:
"pci_mmcfg_init marking 256MB space uncacheable."
Some Googling found me the following link:
https://partner-bugzilla.redhat.com/show_bug.cgi?id=581933
There are apparently performance implications due to this issue.
Fortunately, the solution is simple: just boot with the kernel parameter
acpi_mcfg_max_pci_bus_num=on
If everyone is already familiar with this, please ignore. :-)
