Hi, since there hasn't been much progress with the bugzilla entry I'm bringing this issue to your attention here. :)
http://bugzilla.kernel.org/show_bug.cgi?id=6398 vanilla forcedeth doesn't seem to support suspend and an ifdown/up-cycle is needed to get it working again after suspend. Francois Romieu's "Awfully experimental" patch is working just fine for me (with message signalled interrupts disabled) and has survived quite a few suspend/resume cycles. So I'd very much like to see (at least partial, with msi disabled) suspend support for forcedeth in mainline.
