[Kernel-packages] [Bug 1623467] Re: Kernel oops when unplugging UVC camera during streaming
Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.8 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
