I'm trying to bisect this right now and then report this upstream, but maybe you already see from the backtrace where this is coming from?
"How to reproduce" is simple: plug an usb stick, then unplug it.
I would say this appeared *after* 3.19rc3, but I have not yet tested thid.
My self built 3.19-rc4 does not have the problem. From your description above, there is no need to mount the device. Is that correct?
Exactly. Just plug -- I wait until drivers are loaded etc but no mount -- and unplug and the kernel is dead with the BUG, I think the NMI watchdog triggers a panic a few seconds later, but couldn't verify.
I'm almost done bisecting and it looks definitely rc5+
