Hi Victor, I hit what appears to be the same panic in April: https://marc.info/?l=openbsd-bugs&m=155568856220887&w=2

I don't think I've ever seen a program stress OpenBSD as hard as rtorrent does. A while back I came to the conclusion that part of the problem is excessive gettimeofday() in libtorrent, but didn't investigate further. > I would get multiple "re0: watchdog timeout" messages I've gotten many (very, very, very many) of those over four years using re(4), especially in conjunction with rtorrent. Panics rare; usually I only lost network (which only came back with a reboot) and observed serious system performance degradation (as in keyboard/mouse barely worked). Reading the archives and cvs log it seems that there have been many race conditions in the driver, some of which have been fixed, some which are still present. These show up less than they used to, I assume due to kernel and driver improvements, but it's still bad enough that after years of constantly encountering watchdog timeouts on re(4) I switched to different networking hardware. -- Anthony J.
