Christoph, what were you doing when the crash happened? What OS is this?

Traceback from ehci, CCing gerd and hans

--- Additional comment from Christoph Frieben on 2013-09-08 20:36:48 CEST ---

As stated in the initial report, qemu was launched with boot option

  -drive file=/home/frieben/Downloads/iso/ReactOS/ReactOS-BootCD.iso ,

thus from the standard ReactOS 0.3.15 install media. The crash occurred after confirming that the OS was to be installed to drive C:

However, GNOME Boxes also crashes when booting from the corresponding image file ReactOS.vmdk.

Ah, good catch, thanks for the bug-report. This is a regression in the qemu ehci code in 1.6.0, I've managed to reproduce this, and I've just completed writing a fix for it.

I'll attach the patch fixing this. Cole can you please add this patch to the F20+ qemu builds? I'll try to get it into qemu-1.6.1 .

Upstream discussion has led to a slightly different patch.
