If the box reboots, this sounds like a kernel oops. In which case, we'd really need a kernel stack dump to debug it. Which I'm not sure there's a good way to get on OpenWrt without attaching a serial console :( Unless of course you can find a reliable way to reproduce it without too much delay, in which case someone with a serial console can take a look, I guess :) -Toke _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
