Hi,
with a recent -CURRENT and xen-4.6.0, I now see a different crash at boot on

building master without problems.

Hi,
with Xen from git and a recent -CURRENT, I get "interrupt storm detected on
"irq16:"; throttling interrupt source" messages on the dom0 console about once
a second. irq16 is used for ehci:

irq16: ehci0 1229805 6559
Any ideas?

I'm trying to get my feet wet with running the i386 PV -CURRENT kernel under
Xen 4.1. It seems to crash immediately after the kernel has booted. Any ideas?
