FYI - pci_mmcfg_init kernel error after upgrading to 5.6
...long an error I received this weekend after
upgrading two servers to 5.6. Both are HP Proliant DL380 servers
running 64-bit, but one is a G6 model and one 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:

There are apparently performance implications due to this issue.
Fortunately, the solution is simple: just boot with the kernel parameter
acpi_m...
