Jan,

This patch set fix the previous issue we saw from the get_intremap_entry() causing the ASSERT on (table != NULL).  Now the system is booting.

However, I think there are some issues with the interrupt remapping for the USB devices. During dom0 booting, it gave error w/ regarding timeout during loading some USB drivers. Also, lsmod is showing "hid_generic" module is missing.  This resulting in the USB mouse and keyboard are not working.

From xl dmesg, I do not see anything different from before patching.  I am investigating the issue.
