I think they've disappeared because our log rotation is too fast - I've 
now upped it to 30 days. I guess over time we'll figure out what we need 
in this regard, ideally we'd keep logs indefinitely but they're several 
megs per build.

I've kicked off another build for this series and the links in Patchwork 
should update to point to the new job when it's done (probably in the 
next couple of hours).
