My nc6220 loses all its ATA devices on resume. Mine also has a serial console
so I've been able to debug some. Try
http://www.FreeBSD.org/~jhb/patches/ata_reinit.patch (fixes a panic on
resume) and http://www.FreeBSD.org/~jhb/patches/ata_resume.patch (doesn't
lose ATA devices on resume). This gets it closer, but somehow resume is
hanging elsewhere as i still don't get to where I can hit enter on the
(serial) console after this. I have verified that you can use acpi_video to
turn the LCD on and off, so that will be useful once it gets far enough to
run commands during resume. On my laptop at least, though, acpi_video always
thinks all the output devices are off even when they are on.
