[Xen-users] Xen 4.12.1/4.13.0-rc2 unable to load module coretemp

[Bobbi Sanchez <bobbisanchez@xxxxxx>]

Hi,


i am using (Debian10) Kernel 5.3.7-amd64 self compiled with XEN-dom0 Options 
activated and also Xen from source Version 4.12.1 and 4.13.0-rc2 self compiled, 
everything seems to work find but i am not able to load the coretemp.ko module, 
not possible under Xen4.12.1 and 4.13.0-rc2!

If i dont load the xen.gz at boot, so that i only run Kernel 5.3.7 coretemp is 
no problem to load!


Thats the output if i try to load the coretemp module:
