From 5a8660741a8aa19fbf8a5e8a2b3aac88664f4e66 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Tue, 19 Jan 2016 12:44:44 +0100 Subject: ehci: update irq on reset After clearing the status register we also have to update the irq line status. Otherwise a irq which happends to be pending at reset time causes a interrupt storm. And the guest can't stop as the status register doesn't indicate any pending interrupt. Both NetBSD and FreeBSD hang on shutdown because of that.
