Workaround for the corrupted Intel X48 DMAR table
...00 00 00 00 02 01 ................
In line: 0100: 00 00 00 80 00 00 00 00 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,
Neo

RE: Xen-3.2.1 VT-d Support (NOT SURE WHETHER IT''S A BUG OR...)
Hello,
I''m also seeing this exact same problem. I''ve posted on xen-users, but did
not get an answer. Venkat seems to be experiencing the same problem as me. I
have the latest BIOS for my motherboard DQ35JO. (BIOS ver 933) I''m running a
Q6600 as well. It hangs at "Brought up 4 CPUs." I''ve tried all sorts of
combinations of Xen versions and kernels to

eDP screen corruption using linux 3.8 & xen 4.2
Konrad, et al,
I am seeing visual corruption (almost like an interlacing problem) with
i915 under Xen on some platforms using linux-3.8.
See attached file for an example of the visual corruption.
This particular platform is an HP Elitebook 2540p
The same kernel and ramdisk, when booted as native linux does not show this
corruption.
dmesg is attached, as well (out.txt) - but I did not see
