We have the same behavior on s390 when running in a virtual 
environment. The issue is, that the guest physical cpu may be 
scheduled away while a timer runs down. I don't think there's anything 
kvm could do better regerding the soft lockup code. Soft lockup is 
just broken for virtualized environments and needs to be fixed. For 
the time being, just disable it in kconfig.
