Jan,

I have finally root cause the issue.  Here are the two patches that should help fixing the issue.
The first patch fixes the issue with the mouse/keyboard not working while the second patch
add a debug-key to help dumping the IRTE which I used to debug the issue.

I have also include the xl dmesg from both "before" patching and "after" applying patch 1, 2 and the fixes.
These also include the output from debug keys "M,z,i,j"
