It still doesn't work on xen 4.1.4, system reboots at resume. Same on 4.3-unstable (today). Can you give me some hints about using EHCI debug port? I've found some i= nfo on coreboot page[1]. Is there any way to use it without NET20DC device? According to lspci my controller have debug port capability.
