So, what's the plan to fix this? is the plan to fix the toolstack? or put your patch in kernel to kinda workaround it? Is there a way to make a regression test or unit test or something? Does anyone have an idea on what patch would cause the regression? that patch that I pointed out, could it be that one, or should i look at a specific file/line? I can't really just test all of the patches and/or combinations. I'm not really at home with the xen code; and my single xen server is production, so i can really only test in weekends... AL13N
