Hi,

I am not able to boot 4.9-rc1 as a guest on Cavium ThunderX (dt and acpi
mode). Bisecting the guest shows that the problem shows up at

91ef84428a86b75a52e15c6fe4f56b446ba75f93
irqchip/gic-v3: Reset BPR during initialization

If I remove the write to the ICC_BPR1_EL1 register on guest, the VM boots.

Investigating KVM code ...

Thanks

Eric
