after update BIOS, the eject will not automount (it's ok), but using Disks click the "Power off the driver", the driver will auto-mount.

公输目, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-3.XY-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-3.XY-rcZ

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

Christopher M. Penalver (penalvch), I'm sorry.
I can't login in using the new kernel. after type in password at the login screen, it will Stuck!
How can i get the package: linux-image-extra-x.xx-generic, I think it's will useful.

and when I install the new kernel, some problem raise: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-331/+bug/1424238 and "nvidia-331-uvm 331.113-0ubuntu0.0.4: nvidia-331-uvm kernel module failed to build" (this is the Graphics Driver)
$ sudo dpkg -i linux-headers-4.0.0-040000rc4_4.0.0-040000rc4.201503152135_all.deb linux-headers-4.0.0-040000rc4-generic_4.0.0-040000rc4.201503152135_amd64.deb linux-image-4.0.0-040000rc4-generic_4.0.0-040000rc4.201503152135_amd64.deb

Thank you for your understanding.

公输目, as per the previously provided support article, you need to uninstall the proprietary nvidia drivers first before installing the mainline kernel.

[公输目 (yue937)]

Christopher M. Penalver (penalvch), uninstall nvidia drivers && install kernel && install nvidia drivers && reboot
But can't login in... Stuck after type in password && Enter

tty1 login it's ok, restart lightdm can't login in tty7 too.

[Christopher M. Penalver (penalvch)]

公输目, I never said to reinstall the nvidia drivers.
