Ah cool, so we really have 3 bugs to fix in the end. I'm scratching my head again around the channel_reserved() function. The mechanism is theorically simple (what part of the buffer must not be touched) but practically complex (depends on the programmed forward count). Since the same computation is present in channel_may_recv() I wouldn't be surprized that this last one is bogus and ends up saying we cannot receive. Willy
