So, I have a USB audio dongle (currently using ohci, but the same would probably happen with ehci), and if I stupidly decide to unplug it while I'm streaming audio (alsa) to it, mplayer (for example) first freezes ... and if I quit mplayer immediately, things are fine ... but if I try to continue playing (by unpausing/seeking), mplayer goes into an infinite loop of errors trying to write to the (alsa?) audio device, but more importantly, my kernel's (4.8.6) entire usb system seems to break ... I can't even properly load my ehci_pci kernel drivers (it is actually able to load them, but they can't be unloaded... they seem to get immediately hung too... even though the dongle was using ohci at the time) ... my alsa sound is also broken/hung so I no longer get audio ... I'm forced to reboot (and even here it can't power off, I have to force it with the PrtSc buttons). -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
