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 v4.5 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.

Yes, it worked till a couple of weeks ago (not sure about which kernel it was), now all the kernels that are in my grub exhibit the same behavior including the Mainline (v4.5 Wily)

[Jiří Martínek (zwo)]

Hello, I have same issue here. It worked with kernel version 4.4.0-10-generic. I tried 4.4.0-20-generic as the newest without any success.

[Gowthaman Basuvaraj (gowthaman.basuvaraj)]

Solved by Installing Mainline v4.5.2 Wily Kernel

[Paolo Pustorino (stickgrinder)]

Tried Mainline v4.6 yakkety kernel right now, confirm solved.

Gowthaman Basuvaraj, the next step is to fully reverse commit bisect from kernel 4.5 to 4.5.2 in order to identify the last bad commit, followed immediately by the first good one. Once this good commit has been identified, it may be reviewed for backporting. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?

Please note, finding adjacent kernel versions is not fully commit bisecting.

After the fix commit (not kernel version) has been identified, then please mark this report Status Confirmed.

Thank you for your understanding.
