Tested branches:
xen/stable-2.6.32.x
xen/next-2.6.32.x
When trying to boot the current kernel bare-metal it will not load
properly, instead i am prompted with:
panic early exception 0e rip 10:0 error 10 cr2 0
I am seeing this as well. I have been trying to narrow it down a bit,
and it seems to me that the bug was introduced somewhere between
xen-2.6.32.39 and xen-2.6.32.42.
xen-2.6.32.40 also crashes. I think that means that it is either
commits c3dd7941354fa96a71f2613e2c7a1b215fa175dc or
280802657fb95c52bb5a35d43fea60351883b2af (or something in the stable
kernel or else compile differences though both are unlikely). I am
still working on this to confirm which patch it is.
280802657fb95c5 is unlikely - that's just a blkback change.
c3dd7941354fa96 looks plausible.
Yes, xen-2.6.32.40 with c3dd7941354fa96a71f2613e2c7a1b215fa175dc reverted
will boot on bare metal.
