Re: [Xen-devel] PV-shim 4.13 assertion failures during vcpu_wake()

[Sergey Dyasli <sergey.dyasli@xxxxxxxxxx>]

After printing some debug information I see that:

SMP alternatives: switching to SMP code
(XEN) [    1.473056] == d1v1 master_cpu 0, lock ffff83018e315ec8
(XEN) [    1.473120] sched_null.c:344: 1 <-- d1v1
(XEN) [    1.473165] == d1v1 master_cpu 1, lock ffff8301899c2f48
(XEN) [    1.473223] Assertion 'lock == 
get_sched_res(i->res->master_cpu)->schedule_lock' failed at 
...are/xen-dir/xen-root/xen/include/xen/sched-if.h:27

The underlying pCPU was changed for that vCPU and hence the per-cpu lock 
changed as well.

Thanks,
Sergey
