[Xen-devel] [PATCH] Xen on a 32-way and bitops
I was trying to bring Xen up on an ES7000 with 32 logical processors and 16GB of RAM. Xen dies on "Assertion ''offset < size'' failed, line 32, file bitops.c" (see below). I think the assertion should be "offset <size". I have attached a patch that does this.
