What could be the attempts I would try to get rid of this problem. I
tried
setting "Direct" in kernel PCI Access Mode - it works well. However I
want to
use "any" option, which chooses MMCONFIG first...

Please help if someone is able to...

As the message states, it&#039;s a BIOS bug.
Look for an update from your motherboard vendor.

May I ask what motherboard you are using? I get the same error on my
Asus S5A laptop.

The same error occurs on my Benq S72G-110. Its motherboard is Intel
915PM.
It occurs after I upgrade the kernel from 2.6.15 to 2.6.17 as I need
to install the latest ATI driver.
Is there any way to solve the issue?


David Cooke Writes, I get these same messages at boot. Running a new machine
with FC5. Mother board is Intel D945GTP. I have couple of bios fixes
downloaded from

http://support.intel.com/support/motherboards/desktop/d945gtp/

but requires boot from floppy. If you find your MB listed and do decide to update, let
me know if they work so I won't waste time with it.

=========================

上面的做法只是屏蔽了mmconfig
应该是系统共享地址出的bug，以后会改好的吧
