I have rather repeatable (what seems like) deadlock here. I use rtorrent to download stuff. When there are strong seends I can d/l at megabytes per second together on several torrents. The deadlock happens when rtorrent is downloading from such fast torrents and also checksumming already downloaded files.
I tried to panic the kernel and get dump by breaking into debugger from keyboard but I didn't get useful dump, because savecore didn't dump it from swap, maybe next time.
