I didn't get a chance to notice the last good version , because pygrub stopped working (return no data ) right after XSAVE patch (for myself, of course) .

If you¹re using a recent xen-unstable then you might try again with the
current tip. A couple of changes went in recently (including one fix today).

If you're fetching xen-unstable with "hg" and building it, then
you have everything you need to do bisection:
1. hg bisect -r
2. hg bisect -g <known good
version>
3. hg bisect -b <known bad version>
4. build as usual and test
1. if works: hg bisect -g
2. if not: hg bisect -b
5. repeat 4 until first bad version has been isolated
Thanks,
J
