Linux kernel-5.17.x and 5.18.x and early 5.19.x was affected by a regression 
that caused
Dom0 to hang. My Haswell was affected by that regression no matter what version 
of Xen,
so 5.18 kernels not working might not have anything to do with Xen 4.17-rc2 but 
might
be caused by a regression in the Linux kernel that affected some Intel systems.

The regression that caused the hang on Dom0 in Linux 5.17.x and 5.18.x on some 
Intel
systems was first reported here:

https://lore.kernel.org/regressions/YnHK1Z3o99eMXsVK@mail-itl/

and it was resolved here (in the mainline kernel):

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=master&id=72cbc8f04fe2

and the fix arrived in the Linux stable tree at version kernel version 5.19.6 I 
think.

Cheers,
