Hi, I''ve been trying to boot stefano''s minimal dom0 kernel from git://xenbits.xen.org/people/sstabellini/linux-pvhvm.git 2.6.36-rc1-initial-domain-v2+pat On xen-unstable, I get the following WARN_ON()''s from Xen when bringing up the NIC''s, then the machine hangs forever when trying to login either over serial or NIC. (XEN) Xen WARN at msi.c:649 (XEN) ----[

1: IOMMU: properly check whether interrupt remapping is enabled 2: AMD IOMMU: only disable when certain IVRS consistency checks fail 3: VT-d: deal with 5500/5520/X58 errata Patch 1 and 2 are version 2 of a previously submitted, then withdrawn patch following up after XSA-36. Patch 3 is version 3 of a patch previously sent by Malcolm and Andrew. Signed-off-by: Jan Beulich

Hi, I''ve still have problems with ACPI(?) on Xen. After some system startup or resume CPU temperature goes high although all domUs (and dom0) are idle. On "good" system startup it is about 50-55C, on "bad" - above 67C (most time above 70C). I''ve noticed difference in C-states repored by Xen (attached files). On "bad" startups in addition suspend
