It was kernel panicked. Just hard power cycled it, it should be up shortly.

Thanks.

Thanks!

... and then a whole bunch of segfaults/stack traces...

I think it's our friendly usb resets again >.<

Would you happen to know what kind of usb hub build24-b4 has got?

build24-b4 has an older Anker usb hub. Would it help to upgrade it to a Keedox?

I'm willing to be it would. Do we have any spares of those lying around?

Sure. I can swap it out now.

build24-b4 has been keedoxed. Let us know if things look ok.

Thanks.
