[Xen-users] Failed to bring up CPU 1-7 on Xeon D-1518

[Sylvain Munaut <s.munaut@xxxxxxxxxxxxxxxxxxxx>]

Hi,

Trying to boot xen 4.7.0 on a brand new Xeon D-1518

and at boot, I get :

(XEN) Failed to bring up CPU 1 (error -5)
(XEN) Not responding

for each CPU (so 1 to 7).

and then in the dom0, I only see 1 cpu.

If I boot a classic linux kernel, it works fine, I see all 8 cores
(well 4 hyper-threaded cores).

Any idea what's going on ?

Cheers,

     Sylvain
