Randy,
I finally can get the serial port PCI card working,
though it will hangs the Dom0 but it is enough for me at this moment. The
following is the log after applying your
patch.
Thanks,
Neo

Neo,
Can you try
attached patch? I guess you
are using add-on graphics card, right?

It should
be a BIOS bug.
Can you
post your changes in "acpi_parse_one_rmrr" function and panic
information?

hi,
I am trying the Xen unstable on X48 chipset these
days but it failed due to an corrupted RMRR table in the ACPI. The
following is the acpi dump of DMAR.

ff ff ff 7f 00 00 00 00, the RMRR reserved memory region starting address
is even higher than its limit address.
Is there anyway to do a
software workaround for this issue? I tried to simply ignore that entry in
the "acpi_parse_one_rmrr" function, but I hit a panic in function
"iommu_enable_translation".
Thanks,
