What platform are you using? Did you boot up Xen on it before? We didn't encounter this issue. Regards, Weidong -----Original Message----- From: Dietmar Hahn [mailto:dietmar.hahn@xxxxxxxxxxxxxx] Sent: Wednesday, December 02, 2009 10:23 PM To: xen-devel@xxxxxxxxxxxxxxxxxxx Cc: Han, Weidong Subject: VT-d: xen hangs while booting with iommu=1 Hi, I tried xen-unstable from last week with iommu=1 and xen hangs during boot. Xen found 3 drhd structures. After enabling the translation for drhd structure 3 in iommu_enable_translation() line dmar_writel(iommu->reg, DMAR_GCMD_REG, sts | DMA_GCMD_TE); it hangs forever. Attached is the output of the serial console. I hope anyone understanding this better than me can give me a hint ;-). Thanks.
